摘　　要：长春地铁1号、2号线在解放大路站进行换乘,换乘站为三连拱双柱式单层十字交叉联通结构。文章采用有限元方法建立单层联通结构仿真模型,对侧洞法和中洞法2种施工方法引起的地表沉降规律进行仿真研究,优化分析十字交叉互联结构联络通道工法,以期能够提高类似地下互联结构工程的施工效率及安全性。Changchun Metro line 1 and line 2 transfer at Jiefang Road station.The transfer station is a single-story,three-span,and double-column connecting passage and its structure is a cross interchange structure.This paper with the finite element method establishes the simulation model of single-story passage structure,simulating the ground settlement pattern caused by the side hole method and the middle hole method,optimizes and analyzes the construction method of the cross interchange structure connecting passage,so as to improve the construction efficiency and safety of similar underground interchange passage structure.
