在基坑工程中,地下连续墙往往作为其截水、防渗、承重和挡水结构,而槽壁作为地下连续墙的重要一部分,其稳定性将关系到整个地下连续墙的施工质量。结合工程实例,对影响槽壁稳定性的因素进行控制,并对失稳机理进行分析,提出了防止槽壁失稳的应对措施,以保障地下连续墙的施工质量。 In the foundation pit project, the diaphragm wall is often used as the water-cut, seepage-proof, load-bearing and water-retaining structure. As an important part of the diaphragm wall, the stability of the diaphragm wall will be related to the construction quality of the diaphragm wall. Combined with engineering examples, the factors that affect the stability of the tank wall are controlled and the instability mechanism is analyzed. The countermeasures to prevent the instability of the tank wall are proposed to ensure the construction quality of the diaphragm wall.
