本文论述沥青薄膜用于大坝防渗在技术经济方面的好处并提供了在不同条件下应用的实例。二十世纪沥青已广泛地应用在公路建设上,由于它具有不透水的性质,远在三千多年以前这种材料就在水工上起着重要作用。那时,埃及、亚述和印度的文明社会已经把天然沥青用于建筑水库和河堤保护,其中有些工程至今仍发挥着效益。从那时以来,用沥青做为诸如块体、填石和石板等不完整构件的粘合材料建成了许多建筑物。沥青也以整体连续涂层的形式被
This article discusses the technical and economic benefits of asphalt film for dam seepage prevention and provides examples for application under different conditions. Twentieth century asphalt has been widely used in highway construction, due to its impermeable nature, as early as three thousand years ago, this material played an important role in the hydraulic work. At that time, civilized societies in Egypt, Assyria and India had used natural bitumen for the protection of construction reservoirs and embankments, some of which still exert their benefits today. Since then, many buildings have been built with asphalt as a binder for imperfect components such as blocks, rock fillings and slate. Bitumen is also in the form of an integral continuous coating
