混凝上面板堆石坝同碾压混凝土坝一样,是当前水利水电工程比较热门的两种坝型。混凝土面板堆石坝与混凝土坝相比,其优点是:对地基要求较低,较能适应复杂的地质条件;能充分利用当地材料,就近取材,节约水泥,降低造价;减少场外运输量。它与一般土石坝相比,其优点是:坝体体积较小,整体稳定性好;不用土料防渗,节约耕地,施工期受气候影响也较少;施工初期堆石坝体可
Like the roller compacted concrete dam, the concrete-faced rockfill dam is the most popular dam type in current water conservancy and hydropower projects. Compared with concrete dams, concrete face rockfill dam has the following advantages: lower requirements on foundation and better adaptability to complicated geological conditions; full use of local materials, near-site material, cement saving, lower cost; and reduction of off-site traffic volume. Compared with ordinary earth-rock dam, it has the advantages of small volume and good overall stability; it does not need soil seepage control and saves cultivated land, but also has less influence on the climate during the construction period. In the early stage of construction,
