| 摘 要： | 江雄水库施工中认为坝区存在较严重的渗漏问题, 由此, 在设计中对河床段坝基采用了上墙 (防渗墙) 下幕(帷幕灌浆) 组合防渗结构, 对两岸坝肩采用了帷幕灌浆防渗结构处理措施。利用渗流理论, 在分析坝区地质条件和概化水文地质模型的基础上, 建立了坝区三维渗流数值模型, 对坝区防渗处理设计条件下(方案Ⅰ和Ⅱ) 的坝基渗漏及渗透变形进行了计算和比较分析。结果表明, 两种防渗方案均可行, 但方案Ⅰ优于方案Ⅱ。

| Abstract: | It is ensured that there is a serious seepage problem in the dam area after engineering geological investigation in Jiangxiong reservior. Thus the treatment methods are adopted in design, which is a combined structure of up-wall ( seepage proofwall) and down-curtain ( grouting curtain) for dam base, and a leakage-proof structure of grouting curtain for left and right shoulders. A 3D numericalmodel is constructed on the basis of geological condition analysis and hydrogeological geological mode generalization by seepage theory. Then the dam foundation seepage and seepage deformation in the condition of leak-proof designing are calculated and compared. The results show that the two p lans all are feasible, and the first one is better than the second |
