摘要
以上海轨道交通12号15标汉中路站为工程背景,采用喷射井点对地下连续墙在浅层砂质粉土中成槽稳定性控制,进行成槽效果、适用性的分析。对后期地下墙施工及类似地质条件、周边环境的深基坑工程地下连续墙施工具有参考价值及指导意义。
Super deep diaphragm wall is constructed in the deep excavation of Hanzhonglu hub station in Shanghai Metro Line 12 and 13. In order to control the stability of the slurry trench in sandy silt clay, jet well-point dewatering is adopted. It could be found that the stability of the trench can be improved significantly by pressure reduction dewatering. It is one of great reference value for this type of projects.
