With the development of urban subway construction,the technology of retaining and protection for excavations close to metro rail lines has become more and more a common problem.This paper mainly analyzes the retaining and protection scheme of the XDG-2017-28 Block Project close to Wuxi Metro Line 4,and confirms that under soil layer conditions in a certain area of Wuxi,the high-cantilever double-row piles structure can meet various retaining and protection requirements and effectively avoid the inconvenience caused by the integral strut system to underground structure construction.At the same time,MIDAS GTS NX finite element analysis software is used to simulate the complete construction process of excavations,which verifies that the retaining and protection system is safe and reliable,and can provide useful references for similar projects.
