| 摘 要： | 在黏土心墙堆石坝坝体内设置灌浆廊道,可使大坝填筑与大坝基础处理同步进行,同时也为大坝运行期提供了检查通道。廊道混凝土受深厚覆盖层沉降变形及混凝土温差影响会产生裂缝,为避免黏土心墙受到破坏,廊道外表面的防渗处理尤为重要。总结泸定水电站大坝工程灌浆廊道外表面的特种防渗处理方法,可为类似工程提供设计和施工借鉴。

| Abstract: | Setting grouting gallery in the body of clay core rockfill dam can make the dam filling and foundation treatment being simultaneously carried out,and also provide an inspection channel during dam operation.As the settlement of deep overburden and the temperature difference of concrete,the cracks will appear in the surface concrete of grouting gallery.For protecting the clay core,the impervious treatment of gallery surface is important.The design and construction of impervious element on the surface of grouting gallery for Luding Dam are summarized herein,which can be as reference to similar projects. |
