ECC core wall rock-fill dam and construction method
The invention discloses an ECC core wall rock-fill dam and a construction method. The ECC core wall rock-fill dam comprises an upstream rock-fill body, a first upstream transition layer, a second upstream transition layer, an ECC core wall, a first downstream transition layer, a second downstream transition layer, a downstream rock-fill body and a slope pressing body which are sequentially arranged from upstream to downstream. The ECC core wall is formed by pouring a super-tough cement-based composite material and mixing according to designed anti-seepage and strength grades, and the thickness of the ECC core wall is determined through numerical calculation and analysis; a deep foundation pit is dug in the ground below the ECC core wall, a dam foundation gallery used for grouting, later operation maintenance and observation is buried in the deep foundation pit, and a grouting curtain is formed below the dam foundation gallery through grouting; and the core wall is made of the super-tough cementitious composites, the deformation adapting capacity and the anti-seepage capacity of the core wall are improved, and the anti-seepage capacity and the tensile strength of the combination portion of the core wall and the dam foundation gallery are enhanced.
本发明公开一种ECC心墙堆石坝及施工方法，包括由上游到下游依次设有的上游堆石体、第一上游过渡层、第二上游过渡层、ECC心墙、第一下游过渡层、第二下游过渡层、下游堆石体、以及压坡体；所述ECC心墙采用超韧性水泥基复合材料浇筑，并且根据设计的防渗和强度等级配合拌制而成，所述ECC心墙厚度由数值计算分析确定；所述ECC心墙的下方地面挖有深基坑，所述深基坑内填埋有用于灌浆、后期运行维护及观测的坝基廊道，所述坝基廊道的下方通过灌浆形成有灌浆帷幕；通过超韧性水泥基复合材料ECC作为心墙，提高心墙适应变形和防渗的能力，增强心墙与坝基廊道结合部位的防渗能力和抗拉强度。
