摘要
为研究盾构法下穿既有地铁车站变形影响,文章采用Mohr-Coulomb准则,建立地层-结构模型,基于ANSYS软件计算盾构法下穿施工引起既有车站结构的变形,分析既有车站结构的变形规律。结果表明:盾构下穿施工中既有车站的结构竖向、横向变形逐渐增大,增加幅度逐渐减小,当盾构下穿至结构侧墙位置时,车站结构变形幅度最大。
In order to study the deformation of shield tunnel passing through the existing subway station,a stratum structure model is established that based on Mohr Coulomb criterion.The deformation rules of existing structures along with shield tunneling are analyzed that is calculated by ANSYS software.The vertical and horizontal deformation of the existing station structure increases gradually during the shield tunneling construction.The deformation amplitude of the station structure is the largest when the shield goes down to the side wall of the structure.
