| 摘 要： | 新疆下坂地水利枢纽工程的坝基为深厚覆盖层,厚度达147.95m,其结构较为复杂,主要由冰碛层、冲洪积砾石层和砂土层透镜体组成,坝基防渗处理难度很大。为此,针对下坂地深厚覆盖层进行了专门的帷幕灌浆现场试验工艺研究,通过对浆液材料、配比、工艺措施和参数经过深入的分析,找出了一套适合于下坂地复杂地层的灌浆施工工艺,为初步设计提供了可靠依据。

| Abstract: | The dam foundation of Xiabandi Hydro-junctionin Xinjiang,which is about 147.95m thick,is a typical deep-thick overburden deposit.It's mainly composed of glacio-fluvial deposit layers,alluvial-diluvial soil and gravel,soil lens.The structure is very complicated.In order to find a a appropriate construction technology of curtain grouting to prevent dam foundation seepage,a specific in-situ test process related to deep overburden of dam foundation was carried out.Through the experiment,the grout materal,mixture proportion,construction measures and parameter have been analyzed in detail. |
