Abstract: Based on comprehension of the causes of the reservoir landslides and influence factors of the surge size and principles o f solid flow energy exchange, the conceptual model test by the water flume was carried out in a typical mountain river reservoir-the Three Gorges Reservoir. The multiple linear regression method was adopted to obtain the relationship among three factors, the landslide slope, the effective contact area between so lid and flow, the rich water depth of the relative initial-surge, the relative initial-surge height, and the relationship between the initial surge height and the progressive surge height. Besides, the error analysis was conducted between the calculated values by the fitted empirical formula and the measured values in the test. The results showed that the fitted empirical formula was reliable.
