Study of damage characteristic of rock-concrete interface

Wang Guan-sh

Abstract

The application of acoustic emission technique in the study of the damage process of rock-concrete interface has been studied.Based on the stress-strain curves and acoustic emission characteristic signal,there is a turning point marked circle which hints that it is possible to find out the initial damage point.The damage mechanism of rock-concrete interface in the damage process has been discussed by damage theory of advance gradually.
