数值模拟方法在黄浦江沿岸基坑围护设计中的应用与分析

Application&Analysis of Numerical Simulation Method in Foundation Pit Retaining Design along Huangpu River

上海黄浦江两岸地块土质具有高渗透性、高压缩性和高含水量等特点,成为区域开发基坑工程中不可忽视的安全隐患。由于基坑围护结构和周边环境的影响与常规地区不同,因此宜采用数值模拟设计方法,对江边深大基坑工程进行三维建模分析。通过对黄浦江某深大基坑计算结果和监测数据比较,给出类似环境参数建议取值,可为同类工程提供经验参考。

The soil on both banks of Huangpu River in Shanghai has the characteristics of high permeability,high compressibility&high-water content,which has become a potential safety hazard in the foundation pit engineering of regional development.Because its impact on the retaining structure and surrounding environment of the foundation pit is different from that in conventional areas,the numerical simulation design method must be used to analyze the 3D modeling of the deep and large foundation pit along the river.By comparing the calculation results and monitoring data of a deep&large foundation pit in Huangpu River,the recommended values of similar environmental parameters are given,which can provide empirical reference for similar projects.
