【摘要】 对水厂铁矿区域工程地质进行了分析 ,采用改进的空心包体应变计对该矿深部边坡岩体进行了 3个水平的地应力测量。结果表明 :最大水平主应力方向为近东西向 ,与华北地区的主应力方向基本一致 ;最大水平主应力的大小为 3.6 8～ 4 .2 6MPa ,最小水平主应力的大小为 2 .0 3～ 2 .6 8MPa ;根据测量结果 ,得到了该矿深部边坡岩体应力分布的规律。更多还原

【Abstract】 The regional engineering geology of Shuichang Iron Mine was analysed. The improved hollow inclusion strainmeter was used in the in-situ stress measurement on three levels in deep slope rockmass. The results showed the orientation of the maximum main horizontal stress was nearly WE, basically identical to that in North China, and the maximum main horizontal stress was 3.68-4.26 MPa while the minimum, 2.03-2.68 MPa. Based on the measurement results, the law of the stress distribution in the deep slope rockmass of the mine was found.更多还原
