摘要

    摘要
  • 摘要: 运用FLAC3D 软件对成都地铁1号线麓山站明挖基坑进行了开挖与支护模拟，得出了基坑施工过程中的变形规律。计算中建立三维模型，考虑流固耦合作用，较真实地还原了实际情况。通过计算得出不同开挖阶段的地表沉降、坑底隆起、土体侧向位移和灌注桩水平变形，为同类工程设计与施工提供参考。
    Abstract: The numerical simulation of the foundation excavation and support on Lushan open-cut metro station of Chengdu metro line 1 was carried out using the software FLAC3D, and the deformation law during the process of foundation construction was obtained. In the course of simulation, a three-dimension model was built and seepage and consolidation was considered to restore the true situation vividly. This simulation offers the settlements of ground surface, uplifts on the bottom of the foundation pit, lateral displacement of soil and horizontal displacement of cast-in-place piles, providing reference for the design and construction of similar engineering.
