Exploration of engineering geophysical techniques in the detection of underground water pipeline diseases
The operation and maintenance of soil near water conveyance pipelines urgently need more comprehensive and accurate daily basic data,as well as better solutions for detecting diseases in water conveyance pipelines during the detection process of hidden dangers in the underground water conduit diseases of the supporting project of Middle Route of South-to-North Water Diversion Project in Beijing.This paper discusses the application of engineering geophysical techniques in the detection of diseases in large-diameter concrete underground water conveyance pipelines.Two geophysical methods,high-density resistivity and seismic micro-tremor survey,were selected to detect hidden dangers in the soil near the water conveyance tunnel.Combining early detection data and geological information,as well as subsequent data inversion,a comprehensive analysis of the structures of soil layers containing hidden water hazards was performed,identifying areas rich in water.Engineering geophysical techniques can provide references for demarcating the range of settlement risk areas and offer new insights for non-destructive testing of underground tunnels.
