摘要
杭州地铁4号线华中路站项目的深基坑工程环境复杂,地质条件差,前期基坑开挖变形较大,存在重大的安全隐患,后续加强风险管控并增加轴力自动系统等措施使围护结构处于稳定状态,并顺利完成结构回筑。
The deep foundation pit engineering environment of Huazhong Road station project of Hangzhou metro line 4 is complex,the geological conditions are poor,the excavation deformation of the foundation pit in the early stage is large,and there are significant potential safety hazards.Subsequent measures such as strengthening risk management and control and adding axial force automatic system make the enclosure structure in a stable state and successfully complete the structural reconstruction.
