【摘要】 利用MTS815.02岩石力学试验系统及破碎岩石渗透仪,采用力控制法测定了煤矸石散体的力学性能,得到了其压缩模量的变化曲线。研究结果表明:煤矸石散体的压缩模量与应力呈线性关系,在蠕变过程中压缩模量随时间减小,且减缓趋势变小,研究结果可为解决破碎岩石的工程问题提供一定的参考。更多还原

【Abstract】 Based on the force controlling method,the mechanical properties of coal gangue granular media are measured with MTS815.02 rock test system and seepage instrument of broken rock to get the variation curve of compression modulus.The study indicates that,the compression modulus has a linear relationship with its stress,and decreases along with time during the creeping.The result can provide some references for the engineering problem of broken rock.更多还原
