| 摘 要： | 用单轴压缩试验测试岩石凯塞尔效应特征 ,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。然而实际岩体几乎都处于三向地应力状态 ,岩石在三向压缩下的凯塞尔效应特征如何 ,直接关系到利用该方法测定的岩体地应力的可靠性。作者根据长石石英砂岩在三向压缩下的凯塞尔效应测试资料 ,对长石石英砂岩的三轴凯塞尔效应进行了分析 ,得到了长石石英砂岩凯塞尔效应与围压的关系 ,三轴压应力状态和单轴压缩应力状态下该类岩石凯塞尔效应的区别 |

| Abstract: | The rockmass geostress is determined according to Kaiser effect of the rock under uniaxial compression. This method is applied widely in rockmass engineering. In situ rockmass is nearly loaded under triaxial compression. How the Kaiser effect of rock under triaxial compression is concerns the reliability of geostress of the rockmass determined by this method. Based on the acoustic emission test data of feldspathic quartz sandstone under the triaxial compression, the Kaiser effect feature of the rock is analyzed in this paper. The relationship between the confining pressure acted on the rock and the Kaiser effect feature of the rock, and the difference of Kaiser effect feature of the rock under uniaxial and triaxial compression are obtained. |
| Keywords: | Kaiser effect of rock triaxial test for rock mechanic property of rock |
