近坝库岸滑坡涌浪-溃坝链生灾害研究进展
Research advances on landslide-induced surge and dam-break cascading disasters near dams
摘要
Abstract
Landslides in near-dam reservoir banks are among the primary geological hazards in reservoir areas.In high mountain canyon regions,the instability and rapid sliding of landslide masses into reservoirs may generate massive surge waves.Under the combined effects of wave impact forces and overtopping-induced erosion,dams face extreme safety risks,posing significant threats to downstream lives and property.The cascading disaster risks triggered by such events have been a longstanding research focus,making it crucial to investigate the disaster mechanisms and chain effects of landslide-induced surge waves,as well as the dam failure processes caused by such waves.This paper reviews the current research progress both domestically and internationally,summarizing experimental and simulation studies on the cascading mechanisms of geological-hydraulic disasters in earth-rock dam reservoir areas within high mountain canyon regions.The analysis covers surge wave characteristics,wave-structure interactions,and overtopping erosion-induced dam breaching.Additionally,the study reflects on and provides insights into future research and practice concerning landslide-induced surge waves and dam-break cascading disasters in near-dam reservoir areas.It is observed that most existing studies focus on landslide susceptibility,stability,and the initial mechanisms of surge wave generation,while overlooking the impact of massive surge waves on hydraulic structures and the risk assessment and management of surrounding vulnerable entities.Future research should be strengthened in the areas of cascading disaster mechanisms,intelligent hazard identification,risk assessment and mitigation,emergency preparedness and response,and relevant policies and regulations.关键词
