摘要
介绍北仑电厂循环水泵房基坑采用逆作法施工的现场监测实例。对基坑开挖过程中地下连续墙体变形、钢筋应力、土压力及沉降进行实时监测。从分析结果来看,围护结构的变形控制在允许范围内,且对周边环境影响较小,说明本工程采用逆作法施工相当成功,达到了预期的效果。
The excavation in circulation water pump-station of Beilun Power Plant, by use of top-down construction method, was proposed. The deformation of diaphragm walls, steel stresses, soil pressures and settlements were monitored, and the monitoring data during the construction were analyzed. The analysis of the monitoring results show that the deformation of excavation is controlled within the allowable range and the construction of excavation has small effect on surroundring environment. Finally, the project by use of top-down excavation is successful and the expected engineering effect is acquired.
