摘要
明珠隧道采用明挖法施工,其基坑具有长、宽、深的特点,施工难度较大,风险较高。为研究隧道基坑变形的特点及工程措施,利用有限元分析程序PLAXIS模拟基坑开挖与支护过程,得出了隧道基坑变形的模拟结果,并与现场监测数据对比分析,总结出基坑变形及分布特点,提出了对应的工程建议及措施。
The Mingzhu Tunnel adopts open cut method for construction.Its foundation pit is long,wide and deep.Therefore,its construction is difficult and the risk is high.In order to study the deformation characteristics of tunnel foundation pit and engineering measures,PLAXIS,the finite element analysis program,is used to simulate the foundation pit excavation and supporting process to get the simulated results of deformation of foundation pit of tunnel,which is then compared with the field monitoring data.Then the foundation pit deformation and distribution characteristics are summarized,and corresponding engineering suggestions and measures are put forward.
