摘要
基坑开挖过程中会对周边环境产生较大影响,特别是邻近既有构筑物、高架桥、市政隧道等敏感结构。在此,以杭州上塘高架桥及香积寺路隧道旁侧某安置房项目基坑工程为例,运用二维有限元数值分析软件,模拟了基坑施工对市政设施的影响,并结合施工实测数据验证了数值分析的有效性,对控制既有高架桥及市政隧道旁侧基坑变形提出了建议,可供类似工程参考。
In the process of foundation pit excavation,the surrounding environment will be significantly affected,especially in sensitive environments such as adjacent existing structures,viaducts,and subway tunnels.Taking the Foundation Pit Project of an Resettlement Housing Project Adjacent to the Hangzhou Shangtang Viaduct and Xiangji Temple Road Tunnel as an Example.Using two-dimensional finite element numerical analysis software,this study simulated the impact of foundation pit construction on municipal facilities.It also validated the effectiveness of numerical analysis by comparing the results with on-site construction measurements.Based on the findings,recommendations for controlling deformations in foundation pits adjacent to existing viaducts and municipal tunnels are presented,offering valuable insights for similar engineering project.
