锚杆支护吸能调控效应理论解析与数值模拟OA北大核心CSTPCD
Theoretical analysis and numerical simulation of energy absorption and control effect of bolt support
为揭示锚杆的支护吸能调控效应及巷道围岩能量场分布规律,采用理论分析、数值模拟方法研究了锚杆支护巷道围岩能量分布特征.首先,采用经典的弹塑性理论及能量守恒定律,分析了支护巷道围岩弹性变形能、耗散能和外力功之间的关系,给出了锚杆吸能表达式;其次,基于有限差分FLAC3D软件及内嵌的Fish语言编程,开发了能量单元模块,模拟揭示了锚固体的预应力扩散和释能特性;再次,通过单元网格遍历循环的方式计算了巷道围岩中各岩体单元的能量,获得了巷道围岩总变形能、弹性…查看全部>>
To reveal the energy absorption and regulation effects of bolt support and the energy field distribution in roadway surrounding rock,theoretical analysis and numerical simulation methods were employed.Firstly,using classical elastoplastic theory and the energy conservation law,the relationships among elastic deformation energy,dissipated energy,and external work in supported roadway surrounding rock were analyzed,deriving an initial expression for bolt energ…查看全部>>
