How to enter the radius of the surveyor s vertical curve with 0?

The intersection method should be the simplest and most accurate input method, that is, the intersection coordinates of the road are input, and then enter the curve elements between the intersections, your curve element is the radius and the circular curve is long, there should be no problem, unless your road is more special, can not be entered with the intersection method.

Curve measurement is to calibrate the curve on the drawing on the ground for construction. It is a commonly used method in construction surveying, and it is also an important technology in surveying. Do you know what types of curves there are, and what are the different types of curves to measure and set curves?

1. Types of curves:

Curves are divided into planar curves and vertical curves.

a) Planar curves:

1. Arc curve: A curve with a certain radius is called an arc curve, and an arc curve includes a single curve, a complex curve, a reverse curve and a turning curve.

2. Spiral curve: The transition curve connecting the straight line and the curve is called the spiral curve, and the radius radius of the spiral curve gradually changes from infinity to the radius of the arc curve.

2) Vertical curves:

The convex and convex curves that connect two adjacent slope lines are called vertical curves, and the purpose is to ease the sharp change in slope at the variable slope point.

If the radius of the measurement element line is zero, the input can be based on the actual data.

Generally, when we are not energized, its radius is 0, this is slowly energized, and the number of this energized is getting larger and larger, and its number will change.

How do you enter the surveyor's vertical curve half sister? It is recommended that you log in to the relevant and I will enter it again.

If that gang is electric, you should think of other ways to see if you can introduce it in other ways?

If you measure the radius of an elemental curve, it should be difficult to get an income.

How do I enter the radius of the curve of the measured element with zero? I think if the radius is zero, then the circle doesn't exist.

The radius of the vertical curve of the surveyor's vertical line is zero, how to enter this surveyor? You have to ask the person about the instruction, how do you enter?

Well, you can click on the place you marked, press enter and you can enter.

How to enter thousands of half-day instructions in Guiyang, you can directly click on the general input.

The intersection method should be the simplest and most accurate input method, that is, the intersection coordinates of the road are input, and then enter the curve elements between the intersections, your curve element is the radius and the circular curve is long, there should be no problem, unless your road is more special, can not be entered with the intersection method.

I can't enter 0 for the radius of the question, I don't have a radius, why?

A radius of 0 does not conform to pi, and the collection in the element does not contain points.

Question: How should I enter this as a radius?

Here's how to enter the radius.

This program supports two methods: intersection method and line element method, flat curve parameters. This help is a parameter of the intersection method, and it should be noted that [Note] You must specify the horizontal curve input method when creating a new route, that is, specify which of the intersection method or line element method is used for the corridor.

There is no way to change the flat curve input method when alignment parameters. If you select the wrong one, you can only delete the rebuild.

Enter the list of flat curve parameters, you can see the new, help, and three-point buttons at the top right of the interface, click the three-point button to see the import and clear options, and when you click the multi-check box after a certain item in the list, a new menu will appear, with delete and select all buttons on it, and the functions of each button are explained in detail below.

New] New Starting Point: When using the Intersection Flat Curve parameter, the first element will automatically jump to the New Starting Point interface, as shown in the following figure, the starting point name is "qd" by default, which cannot be modified. Note: The starting point should be at the zh point (straight point) or the straight line segment before the zh point.

New Intersection: When you're done with the starting point, click the New button to add a flat curve element. Enter the horizontal curve element interface, as shown in the following figure.

First, if you want to enter an intersection, you must select "Intersection" (which is the intersection by default) in the Type drop-down list, so that the input is the intersection element. The input method here is similar to that of the Easy Engineering Measurement System, where LS1 represents the length of the first spiral curve and LS2 represents the length of the second spiral. When inputting asymmetrical and irregular curves, the values of ls1 and ls2 are not equal, and if the eased curve does not exist, ls1 enters 0; If the eased curve does not exist, enter 0 for ls2 and 0 if it does not exist.

Enter a positive number regardless of whether you turn left or right. If your route contains incomplete spiral curves, then please check the Include incomplete spiral curves option (for the time being, only partially incomplete spiral curves are supported, which is not perfect, if the calculation error is large, it is recommended to use the line element method to enter this route). When you enter an element and return to the parameter list, you can see the features calculated by the program except for the intersection point before the last element, such as the intersection station and tangent length.

The features of the last intersection can only be displayed until they have been imported).

New end point: The last element in this program must be a point element, to enter the end point, select "polyline point or end point" in the type drop-down box on the home page, and then enter the end point coordinates, as shown in the following figure. If the last element you entered was an intersection element, the program will prompt you when you exit whether to convert the last intersection element to a point element.

Note] The end point should be on the hz point (slow point) or the straight line segment after the hz point.

The starting point must be the starting point of the vertical curve or the point on the line, and the end point must be the end point of the vertical curve or the point on the straight line. The radius is not divided into bumps and bumps, and the software will judge by itself.

Well, how to calculate the elevation of the start and end points.

Using the frequency conversion governor, the motor speed is changed by changing the current frequency, and then the speed of the slurry pump is changed, and the advantage of this method is that the speed of the slurry pump can be automatically adjusted. Frequency conversion speed regulation has been widely used in foreign countries, due to the high frequency conversion speed regulation, it should be promoted in China, but the current application is not widespread.

Is it entered from the first intersection? If not, you need to find a straight line to set the starting mileage.

1 Find the surveyor software on your mobile phone and open it, and after opening, the parameters, programs, tools, and services displayed in the lower row of the interface are displayed.

2 After opening, click on the 3 dots next to each other in the upper right corner, and the new project will appear.

3 Click on the new project, an interface will pop up, select the intersection method in the interface, the line name is the name you want to give you the intersection method you enter, the station prefix is not filled in by default to k (that is, k12+666 this style, if you need to change, enter the required prefix in the station prefix), there is an elevation design line position below, we don't need to move it. Then click Save, and we'll have a new line.

4 After saving, the name of your new line will be displayed on it, if the new line is greater than or equal to two, click on the line name above to change the line, click the parameters at the bottom of the screen.

5 After clicking the parameters below the screen, the screen will display the line parameters, flat curves, broken chains, vertical curves, etc., we click on the flat curve here, and click the "+" sign, in which we can enter the mileage and coordinates of the starting point, after entering the starting point in the input intersection, the intersection needs to enter the intersection station, coordinates, the length of the intensifying curve and the spiral curve, and finally enter the end point, so that we have entered the completion.

I don't look at this when I measure, I just look at the profile view. The elevation of each 20-meter station is calculated in combination with the slope.

I don't understand this now.

First, enter the start coordinates and station, as well as the strike bearing. Highway is composed of straight lines, gentle curves, and circular curves. Each type of line is a line element.

One line element is followed by the next line element to form a route. So after entering the four parameters of the starting point, then enter the first line element number, enter the radius of the two segments of the line into 0, and then enter the length, and the input length depends on the station. Ease the curve, the starting point is 0, the end point is the size of the radius, and the length depends on the data in the table.

The circular curve, the starting point and the end point are the size of the radius, and the length is also the data in the table.

You can create a new txt paragraph letter grinding file from Tanlun, and change the suffix to. zdm<>

Open it and enter it in the format below.

Station - Elevation - Radius, the last two are entered as 0

After you finish, add this file in the [Project Manager Grip], save and exit.

Highway surveying software with good features, not bad for money. Dude, let me tell you, you just need to use the Daoxiang Highway Surveying Software. You can also draw pictures. Don't lie to you Ai It's not bad, I hope you adopt it.
