In order to explore the construction technology of ultra-deep underground diaphragm wall under complex environment and improve the construction quality of underground diaphragm wall,the study takes a subway station project as an example,analyzes the complex engineering environment,constructs three-dimensional construction model of underground diaphragm wall based on Midas GTS NX software,calculates the process parameters,and proposes the construction technology application method.From the trough construction,steel cage hoisting,and concrete pouring,etc.,the construction quality of ultra-deep underground continuous wall is controlled,the construction deviation is effectively dealt with,and the underground construction safety is maintained.
