地层条件对水平受荷桩的受力与变形影响分析

The analysis of force and deformation of laterally loaded pile in different formation conditions

水平受荷桩基础的设计与分析是一个繁琐的过程,特别是地层比较复杂的情况。为了解地层条件对水平受荷单桩受力与变形影响,本文采用有限差分法对受水平荷载的单桩进行受力与变形分析,根据不同的横向地基反力系数的假设、桩尖边界条件计算水平受荷桩的受力与变形。最后通过一个工程算例,将不同条件的计算结果进行比较分析得出地层条件对水平受荷单桩的受力与变形的影响,为桩基础的设计提供参考。

The design and analysis of laterally loaded pile is a hard work especially in complex formation conditions. This paper analysis the laterally loaded pile in different boundary conditions and analysis the stress and deformation of single pile under horizontal load by the finite difference method, under the assumptions of horizontal sub grade reaction coefficient, calculate the level of the pile tip boundary conditions. Finally, compared the results of laterally loaded pile in a engineering project, and provide a reference for the design of pile foundation.
