The most unfavorable effect calculation, internal force calculation, reinforcement calculation and various checks of pile foundation are relatively complex, and the whole design process has a large workload, and the calculation is cumbersome, and the manual design calculation is easy to make mistakes, and the design cycle is long and it is difficult to achieve satisfactory results. With the gradual improvement of pile foundation analysis methods and the increasing progress of calculation methods, it is imperative to use computers for pile foundation engineering design. In recent years, computer systems for the design, optimization and even intelligent design of various structures have been produced, and many of them have entered the practical stage.
However, due to the complexity of the pile-soil system, there are still many practical difficulties in developing a computer design system for pile foundation with relatively complete functions and can be widely applied to general engineering conditions.
**Based on the Ministry of Communications standards "Code for Design of Highway Bridge and Culvert Foundation and Foundation" (JTG D63-2007), "General Code for Design of Highway Bridge and Culvert" (JTG D60-2004) and "Code for Design of Highway Reinforced Concrete and Prestressed Concrete Bridge and Culvert" (JTGD62-2004) as the theoretical basis, using the powerful MFC (Microsoft Foundation Class) class library in VC++, The design and calculation program of highway bridge pile foundation was developed, and the calculation of pile length, axial compressive bearing capacity, internal force and reinforcement of single pile in the design of cylindrical pile foundation was realized.
The research results of the first project enable engineering designers to get rid of the heavy manual calculation, and have important practical value for the design and calculation of highway bridge pile foundation.

Drawing and calculation of bridge substructure and pile foundation?
Dear, hello, I am glad to answer for you the bridge substructure, pile foundation of the drawing and calculation is 1, get a drawing, confirm whether it is a drawing of the pile foundation, whether the position of each pile is clearly marked, the position of the bearing cap. Whether the drawings are complete, whether there are axes, distance labeling, etc. 2. Some drawings will mark the station number of each pile, if there is no marking, the position of the pile can be determined according to the axis.
The annotation of the position, the horizontal axis and the vertical axis, and the order of the cavity are not distinguished. 3. The pile foundation cap has a single pile cap, a double pile cap, a three-pile cap and other multi-pile caps. Mainly look at the number of piles in the cushion cap, and then the cushion cap on the drawing is generally represented by a box.
4. Then look at the number and distance of the pile distribution of each cushion cap in detail. The distance between the center of the two piles and the distance from the center of the pile to the center of the cap are generally marked on the drawing. From this, the size of the cap and the distribution of piles are determined.

Summary. Hello, glad to answer for you! How to confirm the number of bridge pile foundation inspections, 1
The number of test piles for sampling inspection shall not be less than three; 2.When the total number of engineering piles is less than 50, the number used for detection cannot be less than two; 3.The samples provided as a basis are not counted as the number of samples; 4.
For Grade A pile foundations, the number of inspections is 100%.
Hello, glad to answer for you! How to confirm the number of bridge pile foundation inspections, regret Ji Bi 1The number of test piles for inspection shall not be less than three; 2.
When the total number of piles in the front section of the project is less than 50, the number used for detection cannot be less than two; 3.The samples provided as a basis are not counted as the number of samples; 4.For Grade A pile foundations, the number of inspections is 100%.
The role of the bridge foundation is to take all the loads from the superstructure and transfer them and the loads from the substructure to the foundation. Therefore, in order to ensure the normal use of the Antan liquid of the whole bridge, the foundation and foundation are required to have sufficient strength, stiffness and overall stability to prevent excessive horizontal displacement or uneven settlement.

Summary. Friends <>
The allowable error of pile length and pile diameter is usually determined by the relevant standards formulated by the designer according to the specific engineering requirements. In general, the requirements for bridge pile foundation detection are relatively high, and the error requirements are relatively small to ensure the safety and stability of the bridge. In general, the length error of the bridge pile foundation is generally allowed to be within plus or minus 5%, and the pile diameter error is allowed to be within plus or minus 3%.
However, in some high-demand projects, the allowable range of error will be more stringent, or even lower than the above standards. In fact, the detection of bridge pile foundation generally needs to be carried out with the help of some high-precision measuring instruments and professional inspectors to ensure the accuracy and reliability of the test results.

This is a related extension: in addition to the traditional static load testing method hidden beam, there are some emerging testing technologies that are applied to bridge pile foundation detection, such as dynamic load testing, piezoelectric detection technology, acoustic detection technology, radio wave detection technology, etc. These new technologies have greatly improved the detection efficiency and accuracy, and greatly expanded the field of bridge pile foundation detection.
In addition, in recent years, there have been some bridge pile foundation detection technologies based on machine learning and artificial intelligence, which use a large amount of data for training, and learn and analyze data through algorithms, which can identify and improve the damage degree and life of the pile foundation, providing a useful reference for bridge repair and maintenance. The application of these new technologies will effectively promote the development and innovation of bridge safety monitoring technology.
Let me tell you, I am the champion in this industry, this profession, I personally think that surveying can do the work of the constructor, but the constructor may not be able to do the work of professional surveying, and the measurement technology is stronger. It also depends on whether you want to do the measurement of housing construction, or the measurement of roads and bridges, or the measurement of hydraulic engineering, although they are all measurements, the calculation of the main measurement lofting is almost the same. However, different projects, the construction organization is still slightly different, and the technical requirements are also different As for whether the job is good or not, it depends on the family relationship of the landlord. >>>More
This is the same as the data in the corresponding quality inspection form!
