| 摘 要： | 衢州市在狮子口水库除险加固和峡里湖电站拦河堰坝加固改造等工程具有级配不良,大粒径组较多、细粒径组较少、透水性强的特点.通过对坝基存在砂卵石层的老坝防渗加固处理措施的探讨,对帷幕灌浆在砂卵石坝基防渗加固处理的应用进行了总结,建议采用帷幕灌浆解决坝基砂卵石层的渗漏,帷幕灌浆造价低、速度快、对坝体结构影响小、与坝基基岩灌浆容易结合,对水库除险加固效果明显,值得推广和采用.

| Abstract: | Abstract ：The anti-seepage measures for sandy pebble dam foundation are discussed in the paper, and the applied experi- ences in anti-seepage and reinforcement engineering with curtain grouting in sandy pebble dam foundation have been sum- marized, based on the reinforcement cases in Shizikou Reservoir and Xialihu Power Station in Quzhou. Curtain grouting fea- tures itself as low cost, high speed, minimum impact and easy construction. Several key technical problems in curtain grou- ting construction have also been analysis and discussed. Some notes have been given in the end to provide reference for oth- er similar projects. |
