| 摘 要： | 湘潭电厂灰坝至今已运行10余年,坝体排水系统和棱体均已失效,渗漏现象严重.其中2#副坝在85 m高程以下特别严重,渗漏面积较大,为了大坝运行的安全,需对其进行防渗加固处理.采用二维有限元法对2#副坝采取50 cm厚高喷墙处理至基岩面,50 cm厚高喷墙处理至88 m高程,30 cm厚混凝土防渗墙处理至基岩面3种方案进行渗流与稳定计算分析,综合分析推荐采用高喷墙处理至基岩面的加固方案,为加固设计与施工提供了依据.

| Abstract: | Xiangtan Ash Dam has been running for more than ten years,the dam drainage systems and the prism have lost their functions,and leakage is very serious.Especially the No.2 accessory dam has serious leakage below elevation 85 meters,the leakage area is big.In order to ensure the dam safety,the seepage-proof strengthening needs to be treated.Three kinds of methods are used for the strengthening of the dam.The first scheme is to make a 50 centimeters thick high-pressure sprayed wall to bed-rock surface,the seco... |
