摘要
介绍了使用ＣＳＤ－６０型滑动变形计在三峡工程永久船闸北坡进行的现场监测试验及其有关成果。成果分析表明：（１）边垃岩体的变形具有明显的分区性，主要变形区被定义为边垃岩体松动区；（２）松动区岩体的变形主要由结构面的“张开位移”构成，“张开位移”平均占测孔的累积变形的６６．７％：（３）岩体的变形量与开挖强度关系密切；（４）监测区段边坡是稳定的。
The monitoring work and related observations were conducted in the north slope of the permanent shiplock of the Three Gorges Project by sliding deformeter. The interpretation of the observed data indicates that: (1) the rock mass in the slope deformed mainly in a shallow belt underneath the excavation surface, termed as disturbed zone, (2) the deformation of the rock mass in disturbed zones was mainly composed of opening displacement of primary structure planes, constituting 66.7% of total accumulative deformation on average, (3) the magnitude of deformation is closely related to the excavation intensity ,(4) the slope is stable in the monitoring region based on the analysis of deformation trend.
