我国现有8.7万余座水库,大多建于20世纪50～70年代,限于当时的经济社会条件制约,普遍存在防洪标准低、工程质量差等缺陷,加上长期维修养护不够,其中约40%为病险水库。病险水库不仅不能正常发挥效益,而且存在很高的溃坝风险,严重威胁下游公众安全与经济社会的可持续发展。定期开展水库大坝安全评价,了解大坝安全状况,以便有针对性地采取措施,对确保大坝安全和公共安全具有十分重要的意义。
China’s existing 87,000 reservoirs, mostly built in the 1950s and 1970s, were limited to the constraints of the economic and social conditions prevailing at the time. Flood control standards were generally low and defects in engineering quality were poor. Coupled with the long-term maintenance and repair problems, about 40% For the dangerous reservoir. The reservoir not only can not benefit normally, but also has a high risk of dam failure, which seriously threatens the downstream public safety and the sustainable development of economy and society. Carrying out regular evaluation of reservoir dam safety and understanding the status of dam safety so that targeted measures can be taken are of great significance in ensuring dam safety and public safety.
