Design and Analysis of Deep and Shallow Foundation Pits

以上海市杨高路隧道项目深浅坑基坑设计为例,采用Plaxis有限元软件和同济启明星设计软件对基坑围护结构进行建模分析.结果表明:采用上述2种软件得出的深浅坑围护桩内力和变形计算结果要大于最终基坑实测结果,说明此设计方法安全可信.

Taking the design of deep and shallow foundation pits in Shanghai Yanggao Road Tunnel Project as an example,the enclosure structure of foundation pit is modeled and analyzed by PLAXIS finite element software and Frws7 design software.The result shows that the calculated results of the internal force and deformation of enclosing piles of deep and shallow foundation pits obtained by the above two kinds of software are larger than the final measured results of the foundation pit It is explained that the design method is safe and reliable.
