地下连续墙在地铁站基坑支护中的应用

Application of Slurry Wall in Foundation Pit Support of a Subway Station

文中以华中某岛式地铁站为例,结合勘察设计报告的土层分布情况对支护方案进行比较分析。结果表明,地下连续墙在地铁站基坑支护中在挡水、沉降控制、挡土等多方面均具有明显优势,且造价未大幅增加,可在地铁站基坑支护中进行大力推广。

Taking an island subway station in Central China as an example,the paper compares and analyzes the support schemes by combining the soil layer distribution reported in the survey and design.The results show that:the underground diaphragm wall has obvious advantages in retaining water,settlement control,retaining soil and other aspects of the subway foundation pit support,and the cost has not been greatly increased,so it can be vigorously promoted in the subway foundation pit support.
