There is still a small problem, and there is still a problem

The design of the pile foundation is divided into two parts. One is the calculation of the cushion cap, which is basically the previous formula to calculate the stress state at the bottom of the cushion cap

Then the bearing capacity of the pile under the cap is checked, simply put, the sum of the bearing capacity of all piles is greater than the upper load. However, under the action of eccentric vertical force, because the force of each pile is different, it is necessary to check whether the force of each pile alone is less than the bearing capacity of a single pile (generally the most unfavorable pile can be checked).

Another problem is to determine the bearing capacity of a single pile, and the characteristic value of the vertical bearing capacity of a single pile should be determined by the vertical static load test of a single pile. In the preliminary design, the characteristic value of the vertical bearing capacity of a single pile can also be estimated by the formula, that is, according to the soil distribution and soil mechanical parameters of the geological survey report, the resistance at the end of the pile and the friction resistance of the pile body are calculated.

There are a lot of contents, and the factors that need to be considered and different situations are also complex, so it is not complete to say in a few sentences here, so if you really want to carry out design calculations, you should still understand and understand the design code, such as the "Code for the Design of Building Foundations" (GB50007-2011).

Answer, support me.

I want to ask you a pure boy to close up and crack the question.

I'd like to ask you a question.

If the special merit is high, it will be left to turn over the river and the sea, power: 115 10% frostbite.

The high the attack, the crystal rush, the power of 125, the continuous use of +20 power, the maximum is 205. That is, you use it continuously, add 20 each time, and when you hit the fifth time, Wei is 205

Then stay treading waves + attack, speed 1 level, hit 864, blkk used. 864 uses restraint, just use it 5 times, and then slash in the air, 864 die, 864 uses high pressure, just 1 time, 2 slashes to kill blkk once, and 2 slashes to kill it. Turtles, sharks I don't know.

Slash in the air, power: 100 hit 864, blkk uses the ordinary system and then condenses the gas, power: 80 Although the power is small, but the grass system is played, and the flight system is good Especially the grass system, the flight system can also be used to turn over the river and the sea

The matching moves are: Turning over the river and the sea, crystal scorching and treading waves, and slashing and condensing qi in the sky, if you replace the condensed qi with crystal turbulence or transparency or water god protection, you can also do it

How should a full-level crystal duck be in Rainbow City.
