摘　　要：在施工监测中,经常会遇到一些超埋深、大口径的地下管线,如原水管、高压燃气管、合流污水管等,因其性质特殊,其重要性不言而喻,均属于施工中的重大风险源;但又因其埋深较大,造成大部分直接监测点无法布设,故需采取一些间接监测点进行监测,如土体深层水平位移、土体分层竖向位移、孔隙水压力等。监测点布设在管线附近的土体内,通过监测土体的扰动变形可以对管线的位移量提前做出预判,起到信息化指导施工的作用,确保监测对象的运营安全。In construction monitoring,it is common to encounter underground pipelines with excessive burial depth and large diameter,such as raw water pipes,high-pressure gas pipes,and combined sewage pipes.Due to their special nature,their importance is selfevident and they are all major risk sources in construction.However,due to its large burial depth,most direct monitoring points cannot be set up,so some indirect monitoring points need to be adopted for monitoring,such as deep horizontal displacement of soil,vertical displacement of soil layers,pore water pressure,etc.Monitoring points are set up in the soil near the pipeline.By monitoring the disturbance and deformation of the soil,the displacement of the pipeline can be predicted in advance,which plays a role in guiding construction with information technology and ensuring the safe operation of the monitoring object.
