摘要:
以太湖隧道施工为依托,基于修正剑桥模型(MCC),借助大型有限元软件ABAQUS,考虑基坑开挖及堤防恢复工序,主要分析了基坑开挖面土体隆起及恢复段堤防竖向沉降。对比规范采用的沉降计算法,考虑施工过程的有限元计算结果与实测值更接近,能更准确的反映堤防变形情况。
Abstract:
Based on the taihu Tunnel construction, based on the modified Cambridge model(MCC), with the help of the large finite element software ABAQUS, considering the excavation of the foundation pit and the embankment recovery process, the soil uplift of the excavation surface and the vertical settlement of the embankment recovery section are mainly analyzed. Compared with the settlement calculation method adopted in the code, the finite element calculation result of the construction process is closer to the measured value, which can reflect the embankment deformation more accurately.
