摘要
以泉州泉府大第商住楼基坑工程为实例,在充分研究深基坑工程概况、地层结构、支护形式及周边环境条件的基础上,基于复合土钉支护的工作原理,运用SLIDE软件对复合土钉支护深基坑进行稳定性分析,以GEO-Studio中的SIGMA/W模块进行变形特征的有限元分析,结果表明该基坑的稳定状态及变形与实际监测结果接近,该方法对基坑开挖支护过程中信息化指导施工具有实用价值.
The foundation pit project of Quanfudadi business-living building in Quanzhou was taken as an example,and based on the analysis of the general situation of the foundation pit project,the formation structures and the supporting types as well as the around environment conditions,software SLI DE was used to analyze the stability of the composite soil nailing supporting excavation in accordance with the working mechanism of the composite soil nailing.The SIGMA/W module of GEO-Studio software was applied to perform a series of finite element analyses on the deformation characteristics of composite soil nailing supporting excavation.The results show that the stability and deformation are close to the field monitoring results for deep excavation.The finite element method is of important significance in information construction for deep excavation.
