龙西陡边坡位于正在修建中的龙羊峡水电站库区,距大坝河道3.6公里,是预计在水库蓄水后最早发生失稳滑动而可能引起涌浪危害的部位,为水电站近坝库岸三个重点监测防范对象之一。一九八六年一月二十五日晚,龙西陡边坡下部坡体失稳滑动,总方量约150万立米。本文对该滑坡的基本特征和形成机制作一说明和分析;以少数几个外部变形观测点的资料为依据,分析其变形发展过程并进一步探讨本区滑坡时间预报的可行方法。
Longxi steep slope is located in the building of Longyangxia Hydropower Station reservoir area, 3.6 km away from the dam channel, is expected to instability after the first reservoir slide instability may cause surge surfacing site for the dam near dam Shore three key monitoring object of prevention. On the night of January 25, 1986, the lower slope of the steep slope in the west Longsail slipped and slid to a total volume of about 1.5 million cubic meters. In this paper, the basic characteristics and forming mechanism of the landslide are described and analyzed. Based on the data from a few external deformation observation points, the deformation and development process of the landslide is analyzed, and the feasible method of landslide time prediction is discussed.
