摘　　要：依据上海市地铁15号线某区间岩土勘察所获得的地层资料,采用惯用法对地铁隧道衬砌内力进行计算与分析。针对地铁盾构施工引起的地表沉降问题,本文分别采用Peck公式计算、FLAC3D软件模拟两种方法对上海地铁15号线某区间盾构隧道施工引起的地面沉降进行了计算与分析,得出了不同地层损失率及不同强度混凝土注浆支护下的地表沉降值,对国内地铁建设具有一定的指导与参考意义。Based on the stratum data obtained from the geotechnical investigation of a section of Shanghai Metro Line 15,the internal force of subway tunnel lining is calculated and analyzed by using the customary method.Aiming at the problem of ground settlement caused by subway shield construction,this paper calculates and analyzes the ground settlement caused by shield tunnel construction in a section of Shanghai Metro Line 15 by using peck formula calculation and FLAC3D software simulation,which has certain guiding and reference significance for domestic subway construction.
