扶壁式挡墙施工简单、经济,应用广泛.但在特殊地形地貌等条件的复杂工况下,受地质及周边环境的影响,需要构建桩锚扶壁式复合式挡墙才能满足设计要求.在桩锚扶壁式复合挡墙的设计上,还没有形成完整的设计理论和规范体系.本文结合某小区边坡支护设计项目的工程实际情况,提出以桩作为承载介质,使用桩锚结构提高地基承载力、抗滑移和抗倾覆能力的桩锚扶壁式复合挡墙的支挡结构.并利用极限平衡法和Midas/GTS有限元软件,对桩锚扶壁式复合挡墙进行设计和数值分析,论证了桩锚扶壁式复合挡墙的结构是合理的,对今后同类工程的计算及设计有一定的参考价值.

The construction of the counterfort retaining wall is simple and economical,and widely used. However,under the complicated conditions of special topography and geomorphology,also by the influence of geology and surrounding environment,it is necessary to construct the composite retaining wall with pile anchor to meet the design requirements. Based on the actual situation of slope support design project of a certain district,a kind of pile-supported composite counterfort retaining wall is proposed,which use piles as carrying medium to improve the bearing capacity of foundation,anti-sliding and a...
