摘要
地下水的控制在地铁车站深基坑工程中起着关键作用,特别是富水砂层条件下的地下工程,地下水的问题至关重要。以哈尔滨市轨道交通3#线二期工程为例,研究富水砂层条件下地铁车站深基坑降水设计及地下水控制问题,并应用MJS工法桩进行地连墙接缝处理并取得良好了的止水效果,降低了基坑涌水涌砂的风险,保证地铁车站深基坑施工的安全。
The control of groundwater plays a key role in the deep foundation pit engineering of subway stations,especially the underground engineering under the condition of water-rich sand layer.The problem of groundwater is very important.Taking the second phase project of Harbin Matro Line 3 as an example to study the dewatering design and groundwater control problems of deep foundation pits of subway stations under the condition of water-rich sand layers,and apply MJS construction method piles to deal with the joints of ground connecting walls and obtain good results.The water-stop effect reduces the risk of water and sand gushing in the foundation pit,and ensures the safety of the deep foundation pit construction of the subway station.
