摘 要:本文提出并验证了一种用于模拟堆石坝大规模滑坡导致的漫顶和溃坝的数值模拟技术。该技术通过一种模拟自由表面及径流的流体动力学模型和计算堆石响应及其变形的数值技术的耦合来实现。同时考虑了坝体内的水流和坝体周边的水流。通过求解几个堆石坝的溃坝情况对该计算方法进行了验证,并获得了试验结果。

Abstract: This paper aims to present and validate a numerical technique for the simulation of the overtopping and onset of failure in rockfill dams due to mass sliding. This goal is achieved by coupling a fluid dynamic model for the simulation of the free surface and through-flow problems, with a numerical technique for the calculation of the rockfill response and deformation. Both the flow within the dam body and in its surroundings are taken into account. An extensive validation of the resulting computational method is performed by solving several failure problems on physical models of rockfill dams for which experimental results have been obtained by the authors.
