乐昌峡水利枢纽库岸滑坡弃渣加固效果分析
Effects of Waste Slags in Reservoir Bank Reinforcement of Lechangxia Water Conservancy Project
摘要
Abstract
The Lechangxia Water Conservancy Project is a key flood control project on the upstream of the Beijiang River in Guangdong.Under varying water levels,the stability of the landslides on the bank of the reservoir is poor.From an economic,environmental,and safety perspective,the dumped material footing scheme is adopted to stabilize the dam bank slopes.Taking Songshanzi landslide as an example,this paper analyzes the distribution characteristics of landslide deformation,the deformation rule of characteristic points,and the stability state before and after reinforcement.The main conclusions are as follows:①The water level variation has a significant impact on landslide deformation and stability.The stability of the landslide is highest at low water level,followed by normal water storage,and the worst at the flood limit water level.②The abandoned material footing reinforcement effectively controls the landslide deformation and improves its stability.The stability is increased by 42％at low water level,28％at normal water storage,and more than 25％at the flood limit water level.③The abandoned material footing reinforcement has the best effect on controlling landslide deformation at low water level,followed by the flood limit water level,and the least effect at normal water storage.关键词
