【摘要】 采用有限单元法,研究了巷道遭遇正、逆、走滑断层错动的反应情况。结果表明,断层的不同类型及不同宽度都会对巷道受力产生影响。巷道在遭遇正断层错动时,很有可能发生大区域破坏;走滑断层错动时主要使巷道断层处形成较大应力集中,两盘内受力较小;逆断层错动时对巷道的影响程度介于前两者之间。更多还原

【Abstract】 With finite element method,the roadway under normal,reverse,and strike-slip fault movements was studied.The results showed that the fault type and width influenced the roadway stress.When the roadway under normal fault movement,larger area damage were likely to happen.Under strike-slip movement,there were more stress concentration around the fault and less stress among two sides.The reverse fault movement influence on the roadway was between the former two situations.更多还原
