为了防止堆石壩上游經过壩体漏水,或当上游來水对水泥具有侵蝕性時,为了防止混凝土壩体被水侵蝕,常在壩体的上游面修筑瀝青防水層,在这一方面苏联早就有了相当深入的研究,並且在实际应用方面也有很多的經驗。在中國的水力樞紐上面使用瀝青防水層尚不多见颐俏伺浜纤缯驹O計方面的需要学習了苏联的先進經驗,结合了国产材料的特性,進行了试验研究。瀝青防水層的类型根据苏联的设计規范按照施工
In order to prevent the upstream of the rockfill dam from leaking through the dam body or when the upstream incoming water is aggressive to the cement, in order to prevent the concrete dam body from being eroded by water, an asphalt waterproofing layer is usually built on the upstream face of the dam body. In this respect, Has long been a very deep research, and practical applications also have a lot of experience. The use of bitumen waterproofing in China’s hydraulic hubs is still rare. The Need for O-Meter Studying the advanced experience of the Soviet Union, combined with the characteristics of domestic materials, conducted a pilot study. The type of bitumen waterproofing is based on the design specifications of the Soviet Union
