摘要

针对目前桩土接触问题及滑坡治理后预应力锚索抗滑桩的受力效果进行评价研究成果还很少，结合现场勘查与工程设计，根据预应力锚索抗滑桩中桩土相互作用特征，引入接触单元并编制有限元程序进行计算。根据抗滑桩锚固段的受力分布、桩体弯矩、位移及预应力因素对预应力锚索抗滑桩抗滑效果进行评价，提出预应力锚索抗滑桩的最佳预应力值，对工程设计具有一定的指导意义。

Abstract

On the basis of in-situ survey and landslide controlling design

a contact FEM program using contact elements is designed in the light of the characteristic of the interaction between piles and soils. Then

the anti-sliding effectiveness of prestressed cable piles is evaluated according to the calculation results of such factors as force-bearing distribution

pile shaft bending moment

displacement and prestress etc. Finally

an optimum prestress value for prestressed anti-sliding cable piles is suggested

which is of significance for guiding engineering design to a certain degree.
