In order to study the V River， climbing form and characteristics of the spread of the landslide surge， based on computational fluid dynamics software Flow-3D and used the finite difference method， the generation and propagation process of the sliding surge along the slope was simulated.Taking the Qian jiang ping Landslide as an example， this paper an a-lyzed the generation， propagation and climbing height characteristics of surge when the large slide enter into V-River.This paper further explored the effects of the different climb-ing slope and water depth to the maximum wave height and the maximum climbing height.The results were listed as follows：1) The simulation results are consistent with the ob-served data； 2) Climbing slope has great influence on the surge climbing height， The gener-al surge run-up formula calculation results is small， may significantly underestimate the value of climbing surge.3) The maximum wave height increases first and then decreases with the increase of water depth.
