Description	The construction technology of metro station is particularly critical, especially in loose soft stratum with complex construction environment. Based on the construction of Liyang road interchange station of Shanghai metro Line 10, this paper studies the influence of diaphragm wall construction and deep foundation pit construction on metro interchange station and protection technology. Firstly, this paper discusses the mechanism of groove wall instability and the relationship between stability and slurry specific gravity in grooving construction of mud retaining wall from both global and local aspects. Then the key technology and protection measures for grooving of diaphragm wall are put forward. In addition, the constitutive model of station soil, reflecting the unloading rebound effect of foundation pit excavation, is used to simulate and analyze the dynamic process of foundation pit excavation, which is to obtain the quantitative relationship and regularity of influence of foundation pit excavation on metro interchange station.
