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 self-evident 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.
