| Abstract: | The principle,method and techniques of Kaiser effect to measure initial stresses in rock are described.According to the elastic mechanics theory,the basic equation of ground stress at rock measuring point is derived.Through preparing samples on 6 special directions and experiment to observe acoustic emission,the unilateral plus stress values on each direction and their azimuth angles and obliquities of three principal stress directions are obtained.The results of the experiment are of reference for engineer... |
