Abstract本文对青海省龙羊峡水电站库区大型和巨型滑坡的形成条件及诱发因素进行了全面的论述。提出了形成条件的三要素,即经过超压密作用和盐类胶结的半成岩湖相地层;颇为发育的构造裂隙和层间错动面;高达300~400m,陡达35°~50°以上的阶梯状边坡。在三要素同时满足的前提下,诱发因素——黄河的下切旁蚀和地下水长期缓慢作用方能触发滑坡。同时对半干旱地区大型、巨型滑坡发生的必然性进行了探讨。
Other AbstractIn the paper the author took a comprehensive disscussion about formative condition and induce of large and huge landslide in Long-Yand Gorge Hydro-ecletric station, Qinhai province, and resulted three elements of formative condition as follow:
1).Half-Rocked facies stratum, which had been supper-compressed and salf-cemented.
2).Very activited structure fissure and cirsscross surface among the stratum.
3).Slope in step shape, which height is 300 to 400m, and slope reaches from 35°to 50°.
Under these three condition, landsildes can been actived effect by induce factors, downcutting and side-ersion of Yellow River as well as effect of underground water, Also, inevitability of large and huge landslides in semi-arid area has been reas论earched in the article.
