【摘要】 右岸船闸下游段在一期边坡开挖(高程340～260m)中,于2003年4月15日在1+016～1+080段发生座滑,其变形机制复杂。本文利用边坡和排水洞开挖揭露的地质条件,阐述了座滑体及其边界条件和形成机制,并对特定岩体及其结构面的力学强度进行了反演。
【Abstract】 A slide happened on the excavated slope of the downstream section of the fight bank ship lock of the Longtan Hydroelectric project during the first stage slope excavation(at E1.340～260m)in April,2003.The deformation mechanism of this slide is complicated. This paper has made exposition of the deformation mechanism of the side slope and boundary conditions on the basis of analyzing on the geological conditions exposed during the slope and drainage tunnel excavation,in addition,an inversion analysis on mechanical strengths of particular rock mass and it’s structural plane has been made.
【Key words】 shiplock slope； slide； boundary conditions； deformation mechanism； inversion analysis；
