利用混凝土或沥青混凝土修建的不透水面板,越来越多地被应用在堆石坝工程中,并具有向高坝发展的趋势,也是当前坝工建设上引起普遍注意和研究的问题。根据以往的实践,一般认为,防渗体的设计和施工,是不透水面板堆石坝的关键所在。到目前为止,中小型水库堆石坝的面板,仍是参照已建工程的实践经验,拟定面板和堆石坝体断面,在文克尔假定的基础上,利用初参数法进行计算,手算工作量较大,且很容易出错。
The impervious panels constructed of concrete or asphalt concrete are increasingly used in rockfill dam projects and have the tendency to develop into dams. They are also the problems that have caused widespread attention and research in dam construction. According to past practice, it is generally believed that the design and construction of anti-seepage body is the key to impermeable face rockfill dam. So far, the panel of small and medium-sized reservoir rocksfill dams is still based on the practical experience of the built projects, and the section of the face plate and rockfill dam is drawn up. On the basis of the Winkel assumption, the initial parameter method is used to calculate, Heavy workload and error-prone.
