| 摘 要： | 本文介绍和分析了应用岩石声发射凯塞效应在实验室测量地应力的方法和存在的问题。指出，Ｋａｉｓｅｒ效应测定的地应力与现场实测值相近，Ｋａｉｓｅｒ效应存在于岩石变形的弹性阶段，记忆现今应力，围岩对Ｋａｉｓｅｒ效应影响较小，Ｋａｉｓｅｒ效应方向独立性近似成立。

| Abstract: | According to the basic principle of Kaiser effect,this article investigates the way to determinegeo-stress in laboratory and analyzes some problems unsolved up to now. It is presented that the geo-stressdetermined on the basis of Kaiser effect approaches to its numerical value determined in site. This effect isproved coming into existence in the elastic stage of deformation of rock and available to remember the existingstress,and is affected slightly by surrounding rock with its orientation found nearly independent. |
