缺失第⑥硬土隔水层的深基坑承压水处理技术研究

A Study on Treatment Scheme of Confined Water for Deep Foundation Pit Without No.6 Stiff Soil-Aquiclude

针对第⑥硬土隔水层有缺失的上海地铁M8线黄兴路车站深基坑,分析了车站深基坑工程特点,提出了基坑承压水处理方案,从技术、经济、对环境影响等角度对方案进行了比选,并将比选后方案应用于工程实际,结果显示该方案切实可行。最后,对基坑承压水的处理提出了一些建议。

Based on the deep foundation pit of Huangxing road station without No. 6 stiff soil-aquiclude in Shanghai metro line MS, the characteristics of the deep pit project was analyzed, and the treatment schemes of confined water for foundation pit were presented. The schemes were compared and selected from viewpoints of .technology, economics and their influence on environment, and the selection scheme was applied in practice engineering. The result shows that the scheme was reasonable and feasible. In the end, some suggestions for the treatment scheme of confined water for the deep foundation pit were presented.
