摘　　要：在软弱地层地区施工联络通道及废水泵房,无论采用地面加固还是冻结法,都会有较大的施工风险,尤其废水泵房的施工是高风险点。鉴于近期部分地区地抶区间施工事故的发生,明确不同条件下区间废水泵房集水池的设置原则,以减少后续施工的风险。在正常情况下应保证区间废水泵房集水池的有效容积;特殊情况下区间废水泵房集水池的有效容积进一步压缩;另外也可考虑采用一种新型的轨行区内置式泵房方案,将区间废水泵房设置在轨道下方区域。Whether the ground reinforcement or freezing method is used to construct the con nection passage and wastewater pumping station in the weak stratum area, there will be greater risks, especially the construction of wastewater pumping station in the metro tunnelis a highrisk. In view of the recent occurrence of metrosection construction accidents in some areas, the author wrote the paper to clarify the setting principles of the collectingwell in different conditions, so as to reduce the risks of the future construction. Under normal conditions, the effective volume of the collecting well in the section wastewater pumping room should be guaranteed. Under special cir cumstances ,the effective volume of the collecting well is further compressed. In addition, it can al so be considered to adoptthe internal pumping station, a newway to set the section wastewater pumping station in the area below the track.
