基于梁模型的正断层应力分析与ANSYS数值仿真

Analysis of Normal Fault Stress and ANSYS Numerical Simulation Based on Beam Model

煤层开采经常遇到断层,依据梁模型就煤岩正断层处进行应力分析和ANSYS数值模拟,认为断层处应力值仅与断层处的载荷集度及断层倾角有关,ANSYS数值分析结果与梁模型理论分析基本一致,可为顶板破断支护提供参考。

Coal mining can often encounter with faults.Based on beam model,stress analysis and ANSYS numerical simulation are made for the normal fault of coal rock stratum.The fault stress value is considered to have relation with the load concentration and inclination angle of the fault.The ANSYS numerical analysis has draw a conclusion that is basically in conformity with that by the theoretical analysis of beam model,and therefore,can be used as reference for the support of broken roof.
