V型河道下滑坡涌浪的传播与爬高
Propagation and climb height of surge triggeredby landslide in V-river
摘要
Abstract
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 Qianjiangping Landslide as an example, this paper analyzed 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 climbing 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 observed data;2) Climbing slope has great influence on the surge climbing height, The general 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.关键词
