【摘要】 地应力的大小是引起各种地下或露天岩土开挖工程产生岩爆破坏的根本原因。文章以岩石地应力模拟理论为基础,结合某水电站导流洞隧道开挖过程,采用ANSYS有限元分析软件对岩石地应力场分布变化情况进行计算分析,分析结果合理。更多还原

【Abstract】 The terrestrial stress is the principal reason for resulting in rock outburst in open or underground rockmass excavation.In this paper,the software of ANSYA finite element is applied for calculation and analysis on distribution and variation of the rockmass terrestrial stress in accordance with the simulation theory of the rockmass terrestrial stress and in combination with the excavation of the diversion tunnel of one hydropower project.The analysis results are proved reasonably.更多还原
