一、前言研究对象位于正在建设中的黄河上游公伯峡水电站库区,地处青海省尖扎县上游约1.5km处,与县城隔河相望。滑体上有省级公路穿过,且滑体前缘剪出口大部分低于电站正常蓄水位。因此,若电站按正常工期于2004年下闸蓄水后,该滑坡的稳定性、变形破坏方式及可能产生的社会危害和影响已引起有关方面的高度重视,认识上也出现了一些不同 I. Introduction The research object is located in the reservoir area of ​​Gongboxia Hydropower Station, which is under construction. It is located at about 1.5km upstream of Jianzha County in Qinghai Province, across the river from the county seat. There is a provincial highway on the slippery body, and most of the shear front of the sliding body is below the normal water level of the power station. Therefore, if the stability of the landslide, the way of deformation and damage and the possible social harm and influence of the landslide have been paid great attention by the relevant parties after the hydropower station shut down in 2004 according to the normal construction period, some differences have also appeared in cognition
