HML磷矿露天边坡岩体力学参数测试及折减方法

为了对HML露天矿进行边坡稳定性分析,需要全面了解边坡地质情况和获取可靠合理的边坡岩体力学参数。通过室内岩石力学试验测量得到了HML矿山边坡岩体的抗拉强度、泊松比、弹性模量等力学参数。并采用几种基于室内岩石样本试验和工程地质资料相结合的岩石力学参数的折算方法,对测得的HML边坡岩样力学参数进行处理,得到了可用于实际工程分析和建模计算的较为合理、准确的岩石力学参数。

Rock mass mechanics parameters test and reduction method of HML Phosphate Mine Open-Pit Slope

In order to analyze the slope stability of the Huangmeiling Open-Pit Mine, it is necessary to comprehensively understand the geological conditions of the slope and to obtain reliable and reasonable mechanical parameters of the slope rock mass. The mechanical parameters such as tensile strength, Poisson''s ratio and elastic modulus of rock mass in HML mine are measured by indoor rock mechanics test. Then the measured mechanical parameters of Huangmeiling slope are processed by several rock mechanics parameters conversion methods based on the combination of indoor rock sample experiment and engineering geological data. Finally, a more reasonable and accurate rock mechanics parameter which can be used in actual engineering analysis and modeling calculation is obtained.
