| Abstract: | The frictional force of pile under load action is calculated according to the proportional relation between the action of pile-side frictional force and pile displacement. Pile-foundation settlement is obtained by summing compressive deformation of pile stem and settlement of pile tip and multiplying the sum with the effective coefficient yq of pile group from the semi-empirical formula. The calculation procedure is simple, and the concept of calculation parameter is clear and easy to master. By the procedure it is convenient to calculate the settlement and verify the design. |
