悬臂式抗滑桩设计参数对其工作性能的影响分析

针对当前悬臂式抗滑桩设计计算的流程,结合地基系数法和有限单元法,以改变设计参数为研究手段,重点分析了桩截面类型、桩截面几何尺寸、桩间距、锚固段岩土体强度和嵌入深度对悬臂式抗滑桩工作性能的影响。探讨了几个重要设计参数选取与悬臂式抗滑桩支护效果之间的关系,提出了悬臂式抗滑桩设计时应遵循的几个重要原则。

Impact Analysis on Design Parameters about Service Behavior ofCantilever Anti slide Piles

Directing toward the flow design of cantilever anti-slide piles,the thesis which is based on foundation coefficient method and finite element method mainly analyzes service behavior influences by changing several design parameters,such as cross-section type,cross-section size,range interval,strength of rock mass in anchorage zone,bedded length,and so on.The relations between the design parameter access and the supporting performance of cantilever anti-slide piles are also discussed in this article.Finally,the thesis presents the recommendations and the regularity which should be followed to the design of cantilever anti-slide piles.
