我国特高拱坝应急能力现状分析OA

The construction scale and technical complexity of super-high arch dams(≥200 m in dam height)in China have leapt to the forefront of the world.Such dams occupy a strategic position in the energy structure.However,such dams generally have the characteristics of complex geologic conditions and fast risk transmission,and face significant security threats under extreme environments.Based on investigations of typical projects such as Ertan Hydropower Station and Baihetan Hydropower Station,this paper systematically sorts out the current situation of China's super-high arch dams in five dimensions of emergency system,emergency rule of law,emergency mechanism,emergency plans and emergency support.This study finds that there exist prominent problems in emergency capability of super-high arch dams,such as the lack of effective river basin linkage,the weak pertinence of emergency plans,and the poor applicability of emergency materials and evacuation systems.This paper hereby proposes a four-dimensional optimization path(specialization,dynamization,intellectualization and resilience),including constructing effective basin coordination mechanism,promoting the application of digital twins and intelligent disposal technologies,and optimizing the resilience guarantee network.These findings aim to provide theoretical support and practical reference for enhancing the risk prevention and emergency response capabilities of super-high arch dams.
