摘要:
为获得不同埋深下具有岩爆倾向性的灰岩相似模型,引入岩爆能量原理建立岩爆相似准则,参考原岩相关参数结合岩爆相似准则推算相似模型对应的原岩目标相关参数。引入岩爆倾向性指数、弹性能和耗散能,以石英粉含量、重晶石粉含量、石膏水泥质量比、水含量为影响因素,采用4 因素5水平的正交试验方案,进行单轴抗压试验得到各项参数。对试验结果进行敏感性分析及多元线性回归分析,将不同埋深下灰岩相似模型参数带入线性回归方程,并考虑敏感性分析结果对材料配比进行优化,得出不同埋深下灰岩相似模型优化配比及物理参数,为灰岩室内研究提供参考。
Abstract:
In order to obtain the similarity model of limestone with rock burst tendency under different burial depths, the principle of rock burst energy was introduced to establish the similarity criterion of rock burst, and the relevant parameters of the original rock target corresponding to the similarity model were calculated by referring to the relevant parameters of the original rock and the similarity criterion of rock burst. The rock burst tendency index, elastic energy and dissipation energy were introduced. The quartz powder content, barite powder content, gypsum cement mass ratio and water content were taken as the influencing factors. The orthogonal test scheme of 4 factors and 5 levels was used to carry out the uniaxial compression test to obtain the parameters. Sensitivity analysis and multiple linear regression analysis were carried out on the test results. The parameters of limestone similarity model under different buried depths were brought into the linear regression equation, and the material ratio was optimized considering the sensitivity analysis results. The optimized ratio and physical parameters of limestone similarity model under different buried depths were obtained, which can provide reference for indoor research of limestone.
