悬坝渗流分析理论公式

本文称坝底孔隙压力等于大气压力的土石坝为悬坝。悬坝渗流场的形态与非悬坝的大不相同。可惜至今尚无理论公式可用于悬坝渗流。本文提出了此课题的系统的计算公式,并展示出一个应用实例。由此发现用本文理论计算的结果同原体观测、现场原位检测、室内渗流模拟试验、离心模型试验、和有限元法计算等五种方法获得的结果吻合。从而证明本文的理论公式是正确的,有可靠的精度,对类似工程将是有用的,而且使用简便。

Theoritical Formulae for Seepage Through Suspended Dam

Seepage patterns are quite different between "suspended dam" and nonsuspended dam and there are no theoritical formullae for seepage through suspended dam. Systematical theoritical formulae of this topic is presented and example is given. The theorical results are found to be in good agreement with results obtained by other methods - prototype observation, centrifuge model, analogous seepage model, inspection in-situ and FEM. It is concluded that the theoritical formulae presented are not only correct with reliable precisions, but also useful and simple for this kind of practical problems.
