排水泵站深基坑开挖与变形监测分析

Analysis on deep foundation excavation and deformation monitoring of drainage pumping station

结合某排水泵站基坑工程水文、地质条件差,周围环境复杂且有较大的堆场荷载的情况,工程采用了信息化监测手段对基坑的施工过程进行全面监测,并分析了地下连续墙顶水平位移、水平钢支撑轴力、电缆沟表面沉降、基坑周围地下水位和基坑周围土体深层水平位移的变化情况,保证了基坑在施工过程中的安全性。

Combining with the drainage pumping station engineering conditions including bad hydrological conditions, complicated surrounding environment and big piling field load, the paper applies information monitoring methods and monitors the foundation construction process, analyzes changing conditions of underground continuous wall displacement, horizontal steel support axial force, cable ditch surface subsidence, underground water level and deep soil displacement surrounding the foundation and so on. As a result, it guarantees the foundation safety in construcuon process.
