沥青渣油混凝土心墙堆石坝,是一种适用于山区的、以沥青渣油混凝土为防渗体的当地材料坝。目前这种坝型在日本和西欧许多国家已经推广,我国辽宁、吉林及黑龙江等省的水利水电建设中也开始采用。这种坝是土石坝的一种,设计原理同其它土石坝基本一样,其结构型式也和一般土石坝基本相似,大体分为堆石体、过渡区和防渗心墙三部分。与其它土石坝的区别,主要是防渗体所用的材料不同。由于组成坝体的材料性质有别,采用的施工方法也不尽一致。防渗心墙和过渡区多采用机械和人工配合进行施工,堆石体可根据筑坝材料分别采用低层法、薄层碾压法和高层法等方法进行施工。
Asphalt residual concrete core rockfill dam is a kind of local material dam which is suitable for mountainous area and takes asphalt residual concrete as seepage prevention body. At present, this type of dam has been popularized in many countries in Japan and Western Europe. The construction of water conservancy and hydropower in Liaoning, Jilin and Heilongjiang provinces in China has also started to be used. This kind of dam is a type of earth-rock dam. Its design principle is basically the same as that of other earth-rock dam. Its structure type is similar to that of general earth-rock dam. It is divided into three parts: rockfill body, transition zone and impervious core wall. The difference with other earth-rock dams is that the material used for the seepage control body is different. Due to the different nature of the material of the dam body, the construction methods adopted are not the same. The impervious core wall and the transition zone are mostly constructed by mechanical and manual cooperation. The rockfill body can be constructed by low layer method, thin layer rolling method and high layer method according to dam materials.
