Feasibility of GRP to Penetrate Hidden Cave and case Analysis

Abstract：This paper introduce the theory of GRP wave propagating underground, analyses the key parameter which has effect on the GRP work, discusses the feasibility of detecting hidden limestone cave by GRP, and summarizes the GRP wave character of different limestone cave on the basis of concrete field examples.In the end, the paper discusses the problems that are meet in the common GRP work.It is proved by practice that the method of GRP is a rapid, efficient, economic and reliable method to detect the hidden limestone cave.
