摘要
东莞市城市快速轨道交通R2线工程基坑深18.6m。基坑周边环境非常复杂,开挖支护难度极大。结合工程地质条件及地下水情况,采用地下连续墙+内支撑支护方案,并对地表沉降及位移、墙顶位移、支撑轴力、地下水位等进行监测。通过分析监测成果进一步指导施工,以保证基坑及周边建筑安全。
The foundation depth of Dongguan＇s rapid rail transit R2 Route project is 18. 6m. The surrounding of the foundation pit is very complex and it is very difficult to provide excavation support. Considering thegeological conditions of the project and underground water,the scheme of diaphragm wall plus internal support is employed,and the monitoring of surface settlement and displacement, wall top displacement,support axial force and underground water table is carried out. The monitoring result analysis provides further guide for the construction work to ensure the safety of the foundation pit and surrounding buildings.
