引子渡水电站面板堆石坝快速施工研究

Research of Quickly Constructing Face Rockfill Dam of Yinzidu Hydropower Station

针对引子渡水电站面板堆石坝修建在非对称狭窄河谷的实际情况,通过对导流、土石方平衡、交通布置、抗干扰措施、下闸蓄水及安全度汛等系统的研究,优化了导流方案,使大坝与溢洪道等建筑物基础开挖的石渣利用率达80%以上,消除了溢洪道开挖和大坝填筑之间的施工干扰,解决了狭窄河谷地区混凝土面板堆石坝的高强度运料难题及后期导流等问题,达到了快速建成该坝的目的。

According to concrete status that face rockfill dam of Yinzidu Hydropower Station will be built on a narrow asymmetrical valley,systematically researched these problems such as diversion,earth-rock balance, communication layout,anti-disturbance measure,closing gates for impounding,safely spend flood period,diversion scheme was optimum,utilization ratio of excavated rock chunk is up to 80%,disturbance between spillway and dam filling was eliminated and materiel conveyance in high intensity was achieved,therefore,the goal that the dam was quickly built was attained.
