| 摘 要： | 用三维数值分析模型模拟了隧道盾构开挖引起的地表沉降的发展过程,分析了地表横向和纵向沉降的动态变化规律,得出了模拟盾构开挖过程的数值模型,并基于Peck公式对地表沉降模拟值和工程实测资料的沉降槽参数进行了对比分析。结果表明FLAC3D模型能有效地模拟盾构掘进过程中的地层开挖效应和沉降规律。

| Abstract: | Development of ground settlement induced by shield tunneling was simulated by 3D numerical model. Ground settlement in both transverse and longitudinal directions was simulated with a step-excavation approach. Based on Peck's formula, the results of numerical model were compared with in-situ measurements in terms of settlement trough, which showed good agreements. It is proved that the model is quite effective to dynamically simulate the ground settlement during the advance of shield tunneling. |
