中文摘要: “5·12”汶川特大地震破坏性强,影响范围广,造成四川省1997座水库不同程度受损,其破坏形式主要有:坝体裂缝;内坡塌陷及滑动;坝体渗漏;放水设施损坏等。阐述了地震造成水库程度损坏情况和影响范围,对震损水库的应急抢险和恢复重建提出了具体指导意见和措施,尽可能地降低震损水库发生次生灾害,减轻灾区经济损失。通过地震灾区10个多月1000余座震损水库的恢复重建实践,已有42座水库完成修复,并取得了阶段性成果。
Abstract:May 12th Wenchuan Great Earthquake has totally caused 1997 damaged reservoirs to different extents in the Sichuan Province. The damage type mainly includes: cracks,inside collapse,leakage in the reservoir area,and Water discharge facilities damage. In this paper, firstly the damaged situations of damaged reservoirs and the impact range was demonstrated. Then, based on the study of the characters of earthquake damaged reservoirs, some detailed suggestions and effective way of emergency management and reconstruction were put forward,by which we can lower economic loss and secondary disaster caused by earthquake damaged reservoirs as great as possible. Through the past ten months’ hard efforts for reconstructing the damaged reservoir, 42 reservoirs have been repaired and stage achievements has been reached.
