| 摘 要： | 针对大理岩进行不同围压状态下的岩石天然与饱和状态的三轴压缩试验,并对其进行强度的分析,得出以下结论：相同围压下,岩石天然强度大于饱和强度;同一状态下,随着围压的增加,岩石峰值强度、残余强度随之增加,但峰值的大小与围压的大小没有直接关系,可通过最小二乘法绘制最佳关系曲线,进而得到大理岩强度的准确表达式。

| Abstract: | In this paper,the triaxial compressive tests on natural state and saturated marble are conducted with a variety of confining pressures analysis.The experiment result shows that the strength of natural rock is larger than the strength of saturated rock under the same confining stress.Under the same saturated state,peak strength and residual strength both increase with the confining stress,but the peak strength is not directly related with confining stress value.At last,the best relationship curve and exact expression are obtained by using the least square method. |
