| 摘 要： | 基坑的突涌与承压地下水息息相关。软土地区某基坑下部存在承压含水层,经验算基坑底板不稳定易产生突涌现象,采用深井管井降水降压,有效地控制了⑤2层承压地下水,消除了地下水突涌隐患,保证了基坑坑底、周边环境的稳定及基坑开挖工程的正常进行,取得了满意的工程效果。

| Abstract: | The inrush of soil and water in foundation pit is closely related with the confined groundwater.The confined aquifer exists under certain foundation pit in soft soil area.Through the checking it is indicated that the floor of the foundation pit is not stable and it is easy to cause the inrushing of soil and water.The method with deep tube wells is used to dewater and the relief of pressure,which effectively control the confined aquifer in ⑤2 layer and eliminate the hidden danger of the inrushing of soil nad water.They guarantee the floor stability of the foundation pit and the surrounding environment and the normal excavation,and the satisfactory engineering results are obtained. |
