摘　　要：用单轴压缩试验测试岩石Kaiser效应特征,进而确定岩体地应力状态的方法,在岩体工程实践中得到广泛的应用。由于运用Kaiser效应法测得的地应力值是新构造应力场最近时期的地应力,对新建西安—南京铁路秦岭越岭地区采用岩石声发射的单轴压缩Kaiser效应法结合微构造法对其地应力场进行研究,得出其现代地应力场总体方向为NE向、各测点处的地应力的具体方向及基本地应力值15 MPa,试验结果与实际情况基本吻合。The in-situ stress of rock mass is determined by Kaiser effect of rock under uniaxial compression. This method is applied widely in rock mass engineering. Based on the recent in-situ stress field by Kaiser effect, direction of modem in-situ stress field, direction of in-situ stress in the location of samples and in-situ stress in the three directions are presented by Kaiser effect of rock under uniaxial compression and micro-fault research methodology in Qinling area along Xi＇an-Nanjing Railway. Modem in-situ stress field is in the direction of northeast, and the in-situ stress gets up 15 MPa. The results by Kaiser effect are consistent with those of field test.
