1概况在工程地质勘探中遥测地下空洞的形状和体积，常用的探测方法有：浅层地震勘探法、电磁波透视法和井中电视法等，在这里我们介绍一个用非常规物探方法——声学方法探测地下空洞的形状和体积的实例．十三陵蓄能电站高压管道倾角50o，全长400多米，文要坐落于安山岩和砾岩中
1 Overview Remote sensing of the shape and volume of underground cavities in engineering geological surveys is commonly performed using shallow seismic surveys, electromagnetic wave surveys, and in-hole television surveys. Here we describe a technique that uses unconventional geophysical methods - acoustic methods An example of detecting the shape and volume of underground holes.
