【摘要】 初始地应力是地下工程围岩稳定与支护结构设计的一个基本参数。详细介绍了平顶山一矿的地应力计算原理,并根据矿区实测地应力资料,得出了计算区域初始地应力场相应的应力回归公式,并且分析了矿井地应力的分布特征。更多还原

【Abstract】 The measurement and calculation are presented to determine the in-situ stresses for Pingdingshan No.1 Mine. Based on the determined in-situ stresses,their distribution characteristics are obtained by using theoretical and statistical analyses. The relationship between in-situ stress and geological tectonism is also studied and some meaniful conclusions are obtained.更多还原
