基于Phase2有限元分析的巷道围岩稳定性研究

Analysis of Roadway Surrounding Rock Based on Phase2 Finite Element Software

在简要介绍Phase2有限元软件原理的基础上,以贵州某煤矿回采巷道为工程实例,建立巷道围岩在自然状态下的数值模型,分析了巷道围岩的位移场、应力场及塑性区分布规律,得到了围岩潜在变形破坏区域。研究结果能为后期的支护设计和加固措施提供一定的参考。

On the basis of a brief introduction about the Phase 2 finite element software principle,take a coal mine's mining roadway of Guizhou as example,establish the numerical model of the roadway surrounding rock in the natural state,analyze the distribution rule of the roadway surrounding rock's displacement field,stress field and plastic zone,obtain the potential deformantion and destruction region of the surrounding rock. The result can provide a reference for the latter support and reinforcement measures.
