| 摘 要： | 红雁池贮灰场挡灰坝修建于20世纪60年代末,已经经过两次加高;由于位于高地震区,且三期子坝基础为未完全固化的灰渣,存在坝基液化和渗流稳定问题。因次无法采用惯常的加高办法进行三期加高;通过设计研究采用碎石振冲桩法及在子坝前设置合理的干滩长度得以解决这些问题。

| Abstract: | The retaining ash dam for HongYanChi Reservoir,built at the end of 1960's,had been raised twice already.Because of the dam foundation was un-solidified ash,the devolatilization of the foundation and seepage in dam body,especially the dam located in the intensive earthquake zone,the phase III can't be raised by common technology.Through research,the problem was solved by adopting gravel pile method and setting reasonable dry beach length in front of the retaining dam. |
