摘　　要：因地下连续墙具有成品止水性好、墙身整体性好等优异性能,越来越多城市建设采用地下连续墙作为基坑支护结构。基于萧山国际机场高铁站施工实例,阐述了在复杂环境及软弱地质条件下,如何进行过程质量管控保证72m超深地下连续墙的施工质量,确保基坑工程施工顺利开展。Due to the excellent performance of the diaphragm wall,such as good water-stopping of the finished product and good integrity of the wall,more and more urban construction uses the diaphragm wall as the supporting structure of the foundation excavation.Based on the construction example of High-speed Railway Station of Xiaoshan International Airport,this paper explains how to perform process quality control to ensure the construction quality of the 72m ultra-deep diaphragm wall under the complex environment and weak geological conditions,to ensure the smooth development of foundation excavation construction.
