拱效应和土压力重分布在桩(墙)锚支护结构概念设计中的应用

The Application of Arch Effect and Soil Pressure Re-distribution on the Conceptive Design of Stake (wall) Anchor Shoring Structure

在概述基坑桩(墙)锚支扩结构计算方法的基础上,介绍了桩(墙)锚支护结构在基坑开挖过程中的几种实例坑壁(桩)变形曲线,拱效应和土压力重分布及其条件,为建立桩(墙)锚支护结构的概念设计提供了思路和支撑.

In this paper, on the basis of summarizing the computing method of base hole stake （wall） anchor branch spreading structure, several kinds of example hole wall （stake） distortion curve of the stake（wall） anchor shoring structure in digging of base hole, arch effect and soil pressure re-distribution and the condition are introduced, so as to provide the thinking route and sustainment on the conceptive designing of constructing take （wall） anchor shoring structure.
