| 摘 要： | 滑坡涌浪是一个涉及滑坡动力学、岩土力学及流体力学等多学科的问题,也是一个复杂的流-固耦合问题。特别是随着大规模水电工程建设的推进,库岸滑坡的涌浪问题成为评价库区滑坡灾害效应的一个重要因素。耦合的欧拉与拉格朗日算法(CEL)在解决复杂流体-固体之间的相互作用时有强大的优势。本文根据前人所做的室内模型试验成果为基础,采用CEL算法进行了模拟和分析,结果表明CEL算法分析结果与试验结果吻合较好,证明了其在滑坡涌浪问题分析的可行性和可靠性。

| Abstract: | Prediction of landslide-generated waves involves the dynamic landslide, geotechnical mechanics, fluid mechanics and other disciplinary fields. Also, landslide induced surge is a complicated fluid-solid coupling problem. Especially with the development of large-scale hydropower project construction, the surge induced by landslide is an important factor for evaluating effects of landslide hazards on the reservoir area. The Coupled Euler and Lagrange algorithm (CEL) has a strong advantage in solving complex fluid-solid interaction problems. Based on the results of a laboratory model test which have been done by other people, and by using CEL algorithm, this paper simulates this whole process. The analysis results indicate that the results obtained by CEL simulation is agree well with the laboratory test, which verifies the feasibility and reliability of CEL algorithm on solve the problems of landslide surge. |
