Multiple Source-Detector Reflected Wave Method in the Intercity High-Speed Rail Tunnel Application

Abstract:

In the tunnel excavation process, often encounter fault belt, soft interlayer and abnormal water-bearing body does not directly predict adverse geological structure, not timely prediction and control these geological disasters will affect the safety of production. In many prediction methods in geophysical technology with nondestructive, accurate, efficient, fast and be recognized, many shot-geophone reflected wave method in different geological conditions on the apparent impedance response, the migrated results can accurately distinguish the lithologic interface, in many projects has been confirmed. The paper introduces the multiple source-detector reflection wave observation system based on, combined with the specific project example, elaborated how the shot-receiver reflected wave method in tunnel face geological disaster prediction in rats.
