摘要
盾构法施工在城市地下工程建设中有着广泛的应用前景。选取西安地铁二号线隧道,建立了盾构施工三维有限元模型,分析了隧道盾构法施工引起的地表沉降,并对影响地表沉降的有关因素进行了研究。所得到的结论对地铁隧道盾构施工具有一定的指导意义。
Shield tunnel is an attractive excavation method in the construction of municipal underground engi- neering.A tunnel in the line No.2 of Xi'an subway was taken as example and 3D FEM model was used to analyze the ground surface subsidence.The conclusions drawn from the analysis can provide valuable reference for the prac- tice.
