摘要
通过对锦屏一级水电站普斯罗沟坝址左岸深部裂缝的发育特点及规律的研究,提出了深部裂缝4种变形模式,即缓剪陡张型、缓倾张剪带型、顺剪反张型和引张型。发现变形的结果是岩体拉张位移主矢量以一定倾角指向河流,正是岸坡卸载特点,这从一定程度说明了深部裂缝的卸荷变形实质,揭示了其成因。
The deep fracture regularity of Pusiluogou left abutment slope at Jinping first stage hydropower station is comprehensively studied; and four deformation models of deep fracture are put forward; they are gentle shear and steep tension, gentle shear-tension belt, steep shear and gentle tension as well as tension respectively. The prime deformation ovctor points to Yalongjiang viver with certain angle, that shows the deep fracture is the result of slope unload, therefore the mechanism of the deep fracture is illustrated some degree.
