How to calculate the friction of pile

1. Now mining is hot again. As a result, the price of graphics card increases, and that of second-hand ones also increases
if it's gtx10606g, the second-hand one is about 1700. If it's 3G, it's about 1300.

2. The calculation of pile side friction is very complicated. The friction coefficient alone is not enough. I ask you how much can be pressed into the completely weathered granite of pipe pile.

3. When the pile moves relatively in the soil after being stressed. The friction between the pile surface and the soil layer and its moving direction is generated.

4. The direction of relative displacement between pile and soil determines the direction of pile side friction. When the soil layer around the pile moves downward relative to the pile, the direction of pile side friction is downward, which is called negative friction.

5. Pile length = pile top elevation - pile bottom elevation
net pile length = pile top design elevation - pile bottom elevation
friction around pile = area around pile × Friction coefficient
area around pile = section perimeter of vertical pile × Pile length

6. The soil profile is composed of layers with different morphological characteristics. These layers are roughly horizontal, which is called soil genetic layer. The formation of soil layer is the result of material migration, transformation and accumulation in the process of soil formation.

7. The general calculation is as follows: the pile top is subjected to vertical force, the pile body is subjected to friction, the pile bottom is subjected to supporting force, and the pile body is subjected to water buoyancy.
