本文介绍了链子崖的裂缝与其成因以及为监视危岩体变形的位移观测工作。应用方差检验和均方连差检验,对八年来的观测资料进行统计分析。确定岩体平均每年向北偏东移动2～3毫米。葛洲坝水库蓄水后,年移动量同向加大到3～5毫米。指出近期一般不致整体滑塌入江,局部崩落还会发生。 This paper introduces the causes and causes of the cracks in chain cliffs and the observation of displacements for monitoring the deformation of dangerous rock masses. Application of variance test and mean square difference test, the eight years of observation data for statistical analysis. Make sure that the rock mass moves 2 to 3 millimeters east to north every year. Gezhouba dam reservoir, the amount of annual move to increase to 3 to 5 mm. Pointed out that the recent general will not slip into the river as a whole, the local caving will happen.
