龙羊峡水电站近坝库岸位于黄河南岸,自坝前起向上游全长15.8公里。岸坡由第四系中——下更新统湖相地层组成,相对坡高达300～500米,中、下部主要为粘土夹砂土。坡前滑坡密布,约占库岸长度的80%以上。由于已发生的滑坡多具有规模大(百万～亿万米~3)、滑速高(大于15米/秒)、滑程远的特点(如 The Longyangxia Hydropower Station near dam bank is located on the south bank of the Yellow River and has a total length of 15.8 kilometers upstream from the dam. The bank is composed of the Middle-Lower Pleistocene lacustrine facies, with a relative slope up to 300-500 meters. The middle and lower parts of the bank are mainly clay-sand soil. Landslide in front of the ramp, accounting for more than 80% of the bank length. Due to the landslides that have occurred, there are many characteristics such as large scale (millions to billions of meters ~ 3), high sliding speed (more than 15 m / s)
