ZHU Chang-ping,YIN Dong-mei,WANG Qi(1.Department of Computer & Information Engineering,Hohai University,Changzhou,2130222;2.State Key Laboratory of Hydrology-water Resources And Hydraulic Engineering,Hohai University,Nanjing 210098)  
Since dam-CT can monitor the dam′s deep interior fast and nondestructively,the technique has been receiving increasing emphasis.This paper introduces the techniques of dam-CT that are based on de-tection of the distribution of elastic waves,electromagnetic waves and electric resistance.In particular,re-search advances in the relatively mature area of acoustic-wave dam CT is reviewed with respect of its feasibility,the working principles,hardware equipment and software techniques.Key problems and the de-velopment trend of the acoustic-wave dam CT research are discussed.
