摘　　要：基于FLAC3D,对广州地铁六号线海珠广场站与二号线间的换乘通道做了三维动态施工力学行为模拟,得到施工过程中地表沉降及既有线的变形和内力的演变规律。研究所得到的结果对换乘通道的设计和施工具有重要的指导意义,同时,为类似工程的施工及模拟提供了借鉴作用。Based on FLAC^3D, this paper simulate the 3D dynamic construction mechanical behavior of the transfer channel between Haizhu plaza station of the 6th line and the 2nd line of Guangzhou metro, and find the evolution rule of grotmd subsidence and the internal force and deformation of existing line structure. The result of this paper is an important direction to the design and construction of the transfer channel, at the same time, this paper can also serve as reference for similar project＇s construction and simulation.
