摘　　要：变形监测目的是确保燃气管线在穿跨越施工时候的安全性,或沉降变形控制在可控的范围之内。但是很多管线埋深较大,加之主干道路不能直接开挖,而且为了保护已有燃气管线还会在管线上修筑盖板沟等等,这些条件均为穿跨越施工中的监测任务带来一定的难度。故此传统的抱箍或将监测点直接布设于管顶上方的方法是不可行的。选择采用间接监测的方法布设监测点来进行变形监测,最后监测数据分析表明间接监测方法是可行的。The purpose of deformation monitoring is to ensure the safety of the gas pipeline when it crosses the construction, or to control the settlement deformation within a controllable range. However, many pipelines have deep burial depths, and the main roads cannot be directly excavated, and in order to protect the existing gas pipelines, the cement board will be built on the pipelines. These conditions bring certain difficulties to the monitoring of crossing the construction. Therefore, the traditional hoop or the method of directly arranging the monitoring points above the top of the pipe is not feasible. Therefore, after research, we use indirect monitoring methods to set up monitoring points for deformation monitoring. Finally, the analysis of the monitoring data shows that the indirect monitoring method is feasible.
