白龟山水库是平顶山市唯一的饮用水源地。从2013年夏季汛期一直到2014年汛期期间,白龟山水库出现了自1958年建库以来持续干旱少雨的年份,水库上游来水量少。造成水库库水位持续下降,跌至死水位97.50 m以下。水库顺河坝出现大量裸露的面积,随着干旱的发展裸露的面积越来越大,形成了许多干缩裂缝。若不及时处理会对大坝安全造成危害。使大坝容易出现滑坡,塌坑,跌窝等险情。文章通过对死水位运行期间发现裂缝的成因分析和处置措施的介绍,为今后解决水库遇到死水位以下运行期提供有力的依据,对大坝安全具有重要的意义。
Baiguishan reservoir is the only source of drinking water in Pingdingshan. From the summer flood season in 2013 up to the flood season in 2014, the Baishan Mountain Reservoir experienced a continuous period of arid and dry conditions since its establishment in 1958, with a small amount of water in the upper reaches of the reservoir. As a result, the water level in the reservoirs continued to drop, dropping below the dead water level of 97.50 m. A large amount of exposed area appears along the dam and a large number of dry shrinkage cracks are formed with the development of drought. If not handled in time will dam safety. The dam is prone to landslides, collapse pit, drop nest and other dangerous conditions. Through the analysis of the cause of the cracks found during the operation of the dead water level and the introduction of disposal measures, the article provides a powerful basis for future operation of the reservoir in the event of a runoff, and is of great significance to the dam safety.
