坑边逆作法施工技术及二维有限元分析的应用

Construction technology of slope-side reversed construction method and the application of 2D finite element analysis

介绍了坑边逆作法的施工技术特点,提出一种经改进的地下坑边逆作主体梁板结构与土体—围护墙结构相分离的有限元分析计算思想,对开挖阶段水平支撑系统进行了数值分析,并对开挖卸载对围护结构以及周边环境的数值进行了模拟分析,供类似工程参考。

The article introduces the construction technological characteristics of slope-side reversed construction method, proposes finite dement analysis calculating method for an improved underground slope-side reversed main beam slab structure separated from soil mass-sheltering wall structure, carries out numerical analysis on horizontal shoring system in the stage of excavation and simulation analysis on the value of excavation load on sheltering structure and surroundings, which to offer a reference for similar project.
