温州厚填土深基坑支护设计分析

Analysis of Thick Miscellaneous Fill Deep Foundation Pit in Wenzhou Area

厚填土和软土地区深基坑安全风险大,合理的基坑支护方案选型至关重要。以具体工程案例为依托,采用有限元数值模拟对该地区填土的处理和基坑支护方案进行研究,并与实际监测数据对比,结果表明,计算模拟结果与实测数据基本吻合,周边保护对象的变形满足规范要求,基坑支护设计方案可行,可为类似工程提供参考。

Deep foundation pits have big risk in thick miscellaneous fill and soft soil area,and appropriate supporting structure is very important.Taking a project as an example,the finite element numerical analysis method is used to analyze the support scheme.By comparing with the monitoring data,the results show that the analysis results is identical with the measured data,and the deformation of the protected objects meets standard requirement,which virifies the feasibility of design scheme,and the project experience can give reference for the similar projects.
