摘要
通过对盾构施工所引起的地表沉降进行了经验公式的计算,并利用有限元软件MIDAS(GTS)进行了施工阶段的数值模拟,将计算值、模拟值与现场实测值进行了比较,并对于经验公式与数值模拟的结果合理性进行了验证.提出盾构隧道施工的横向影响范围,对于周围建筑环境保护和施工安全有指导意义.
The ground surface settlement caused by tunnel shield construction is calculated by the empirical formula.MIDAS（GTS） is applied to the numerical simulation during the construction stage,and the value of simulation is compared with the calculated value and the measured value.The rationality of the empirical formula and the numerical simulation is verified.Thus the scope of transverse of ground settlement due to the shield construction is presented and it has guiding significance for the protection of surrounding building environment and the safe construction.
