盾构下穿道路和铁路的数值模拟对比分析

摘要

Taking Jinbin light trial west section underpass railway line project in Tianjin as the background, it carries on the two-dimensional numerical simulation for the ground settlement owning to the shield underpass road and railway construction, contrasts th%以天津市津滨轻轨西段地下线工程为背景,对盾构穿越道路和铁路施工中引起的地表沉降进行了二维数值模拟,将数值模拟结果与监测数据作了对比研究,阐述了盾构过道路和铁路时引起周围环境变化的异同点,提出了控制地表沉降的措施,研究成果对类似的施工问题有指导意义。
