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.
