摘要

为研究双排桩-锚索结构在软土基坑中的内力变化规律及可行性,本文通过理论计算及数值模拟,以东莞某软土基坑工程为例,对结构水平位移、弯矩等参数的变化规律进行了研究,并将实测值与计算值进行了对比.结果表明,卸荷板可提供一个反弯矩,增加结构稳定性;支护结构水平位移理论及数值计算曲线与实测曲线变化趋势基本相似,变形值均在规范允许范围之内;双排桩-锚索结合卸荷板体系应用于场地受限的软土地区基坑支护效果较好.

Abstract

In order to study the variation law and feasibility of internal forces of double row pile anchor cable structure in soft soil foundation pits,this paper studies the variation law of parameters such as horizontal displacement and bending moment of the structure through theoretical calculation and numerical simulation(taking a soft soil foundation pit project in Dongguan as an example),and compares the measured values with the calculated values.The unloading plate can provide a counter bending moment to increase structural stability.The theoretical and numerical calculation curves of the horizontal displacement of the support structure are basically similar to the measured curves,and the deformation values are within the allowable range of the specifications.This indicates that the double row pile anchor cable combined with the unloading plate system has a good effect on the support of foundation pits in soft soil areas where the site is limited.
