【摘要】 采用水压致裂法在典型向斜构造矿区——甘肃华亭矿区进行了14个测站的地应力实测工作,测站布置在向斜轴部和翼部。根据实测结果分析了典型的向斜构造应力场变化特征;同时采用了FLAC3D模拟软件分析了典型向斜构造应力场特征,实测结果与数值模拟结果均表明在向斜轴部是水平主应力最为集中的区域。更多还原

【Abstract】 This paper applied hydro-fracture method to testing 14 points′ geo-stress in typical syncline tectonic area.These points located at syncline axes and wings.On the basis of test results,stress field variation characteristic in typical syncline tectonic area was analyzed.FLAC3D was applied to analyzing stress field characteristic of typical syncline tectonic.Test and simulation result showed that syncline axes was where horizontal principal stress concentrated.更多还原
