岩石声发射Kaiser效应测试玄武岩地应力应用

On application of rock acoustic emission Kaiser effect in surveying stress of basaltic rock

在减少对岩体的影响因素后,运用岩石的Kaiser效应,以弹性力学理论推导了地应力公式,由该公式可知试样3个主应力的大小、方向,且主应力随深度有增加的趋势,以促进岩石地应力的研究。

After reducing the influential factors on rocks,the paper makes use of Kaiser effect of rocks,infers the earth stress formula with elastic mechanism theory,and concludes that the three main stresses,such as their force,the direction and the main stress,increase along the depth,so as to enhance the research on the rock stress.
