摘要:

为评价柿竹园多金属矿地下露天协同开采后的边坡稳定性,需要全面了解边坡的地质情况与岩石力学参数。通过开展单轴抗压强度试验、劈裂拉伸试验、剪切试验,测量出标准试件力学特性参数,包括抗压强度、抗拉强度、剪切强度及内聚力、内摩擦角、弹性模量等。针对传统岩体参数折算的主观性和模糊性问题,采用基于室内岩石样本试验和工程地质资料相结合的模糊数学法进行折减,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。

Abstract:

To assess the slope stability after underground and open-pit mining in synergy in Shizhuyuan Polymetallic Mine,a thorough understanding of geological conditions and rock mechanical parameters is necessary.By carrying out the uniaxial compressive strength test,splitting tensile test,and shearing test,the mechanical property and parameters of standard specimens are measured including compressive,tensile,and shearing strength,as well as cohesiveness,internal friction angle,and elastic modulus.Given the subjective and fuzzy problems existing in the traditional rock mechanical parameter reduction,a fuzzy mathematical method combining indoor rock specimen test and engineering geological data is used for the reduction,obtaining the rock mechanical parameters that are reasonable and accurate and can be applied in actual engineering analysis and modeling calculation.
