摘　　要：以南宁轨道交通5号线某车站为背景,研究了浅埋地铁出入口过街通道CD法施工变形原因及施工方法,对CD法施工的模拟变形数据与实测监测数据进行对比分析研究。研究表明CD法对周边环境影响产生的变形主要在破除马头门至初期支护施工阶段;施工过程中控制好进尺及时支护能够有效控制沉降发展;当施工时遇基岩裂隙水水量大时可采用注浆施工控制沉降。Taking a station of Nanning rail transit Line 5 as the background,this paper studies the deformation causes and construction methods of shallow buried subway entrance and street passage construction by CD method,makes a comparative analysis on the simulated deformation data of CD method construction and the measured monitoring data.The research shows that the deformation caused by CD method on the surrounding environment is mainly in the stage from the demolition of ma tou door to the initial support construction.The settlement development can be effectively controlled by controlling the footage and timely supporting.Grouting construction can be used to control settlement when the water volume of bedrock fissure is large.
