摘要
通过对上海轨道交通9号线宜山路车站深基坑降水试验结果分析,得到不同土层受降水影响的岩土工程特征,并对个别土层的实测沉降与由室内试验参数进行估算的沉降进行比较,以获得真实的沉降影响状况,指导深基坑的设计和施工。
This paper analyzed the well pumping test results of deep foundation excavation in Yi Shan Road station of No. 9 subway in Shanghai and compared the different affections on geotechnique characteristics of different soil layers induced by the well pumping test. This paper also compared the actual settlement of one soil layer with calculated settlement of this layer by adopting laboratory test results.
