层状岩体在现阶段城市地下工程建设过程中十分常见,对围岩变形特征的影响不同于常规地下工程项目.本文依托某轨道交通环线车站特有的工程地质背景,结合现场实时监测数据,利用Midas/NX软件对车站主体工程所涉及到的7个特征断面逐一进行数值模拟计算,在此基础上总结分析其具体的围岩变性特征,并对监测方案提出改进措施,为类似工程提供借鉴.%Stratified rock mass is very common in the process of urban underground engineering construction at present, and it has different influence on the deformation characteristics of surrounding rock than conventional underground engineering project. Based on the unique engineering geological background of a rail transit station and the real-time monitoring data, the Midas/NX software is used to simulate the seven characteristic sections involved in the main project of the station. On this basis, the specific characteristics of the surrounding rock denaturation are summarized and the improvement measures of the monitoring scheme are put forward to provide reference for similar projects.
