摘要

考虑了土压力的空间效应，分析并计算了冠梁对双排桩支护结构的变形协调作用；考虑了滑移面和排距对作用在前后排桩上的土压力的影响，在弹性地基梁法的基础上，提出了一种新的双排桩支护结构设计计算模型。将理论计算结果与工程实测资料进行了对比分析，结果表明应用该计算模型进行计算，能得到有效的计算结果。

Abstract

The spatial effect of earth pressure is considered; and the deformation compatibility of space that the cap beam applies to the double-row piles support structure is analyzed. Besides

the affection on the earth pressure of both the front and the back row piles due to sliding plane and array pitch is considered too. Based on the beam on elastic foundation method

a new calculation model for a double-row piles retaining structure is proposed. Comparing the calculation results of the theoretical model with the actual observation data

it is shown that the effective calculation result can be obtained by reasonable parameters applied to the model.
