樟坑水库位于赣江二级支流梅花江上游,集雨面积35平方公里,总库容1375万立米,具有灌溉、发电(在建),防洪和养鱼等综合效益。水库于1958年始建,1959年冬按小(一)型规模建成。1961年汛期大坝被洪水冲毁,1963年重建,后经四次加固扩建,达到目前中型规模。由于修建和历次加固扩建中土料及施工质量有问题,致使坝体渗漏严重,渗流逸出点较高,危及坝身安全。多年来,水库被迫限制蓄水运行,不能充分发挥工程设计效益。因此,必须采取有效防渗措施,解决坝体渗流稳定问题。
Zhangkeng Reservoir is located in the upper reaches of the Meihua River, a secondary tributary of the Ganjiang River. It has a catchment area of 35 square kilometers and a total storage capacity of 13.75 million cubic meters. It has the comprehensive benefits of irrigation, power generation (under construction), flood control and fish farming. Reservoir was built in 1958, the winter of 1959 by small (one) type of scale built. During the flood season in 1961, the dam was destroyed by floods and was rebuilt in 1963. After four reinforcement and expansion, the dam reached the medium-sized scale. Due to the construction and reinforcement of the previous construction materials and construction quality problems, resulting in serious leakage of the dam, seepage out of the higher point of danger, endanger the safety of the dam. Over the years, reservoirs have been forced to limit the operation of water storage and can not give full play to engineering design benefits. Therefore, we must take effective seepage control measures to solve the problem of seepage stability of the dam.
