摘　　要：以莞惠城际轨道交通工程项目GZH-5标段中DK32+300~DK32+927.303段为背景,借助ABAQUS有限元分析软件对施工过程进行模拟,研究软弱富水地层浅埋暗挖隧道CD法施工对围岩及支护结构造成的影响,得到了在地下水渗流影响下围岩及支护结构变形规律。然后,针对软弱富水地层浅埋暗挖施工,提出了几点隧道工程设计和施工的相关建议。This paper focuses on the rail transit of DK32+300 to DK32+927.303 of GZH-5 of between Dongguan and Huizhou to study the ground settltment and inner force of support structure of shallow excavation tunnel in weak water-rich layer by CD method by using ABAQUS software to finite element analysis.The deformation law of surrounding rock and supporting structure is obtained under the influence of groundwater seepage.At last,some construction suggestions on design and construction of tunnel engineering are put forward for shallow excavation in weak water-rich layer.
