摘要
采用离散元程序UDEC对某矿山节理岩体巷道锚喷支护效果和围岩及支护结构的作用机理进行数值分析,再现了巷道楔形块体破坏的力学过程,分步模拟了喷浆支护和锚喷支护的不同效果,并系统地研究了节理岩体巷道在喷浆支护、锚喷支护施工后围岩与支护结构的作用机理及力学状态。得出结论:即锚喷支护是解决节理岩体支护的有效手段之一,也证实了UDEC是一种很好的数值分析软件,特别适用于模拟节理岩体的变形问题研究。
Numerical analysis is done on effect of jointed rock mass roadway bolt-shotcrete support and effect mechanism of surrounding rock and supporting structure of a mine by adopt discrete element program UDEC, mechanical process of roadway wedge blocks destroy is reproduced, different effect of gunite lining and bolt-shotcrete support are simulated by step, and research is done on effect mechanism of surrounding rock and supporting structure and mechanical state of jointed rock mass roadway after construction of gunite lining and boh-shotcrete support systematically. Get the result of bolt-shotcrete support is one of effective measures to solve jointed rock mass supporting, proved UDEC is a good kind of numerical analysis software, especially suit to the research of deformation problems simulation of jointed rock mass.
