深切峡谷河道滑坡灾害影响的水动力学分析
Hydrodynamic analysis of river landslide disasters in deep-cut gorge
摘要
Abstract
In this paper, by taking the landslide as the research objea which may be formed at Huashiban tension crack zone in the Tiger Leaping Gorge of the Jinsha River, according to the results of Huashiban slope stability analysis, the volume of landslide is obtained; on the basis of analyzing the landslide hazard characteristics of natural river in deep-cut gorge, the hazards to the plants site area of Liangjiaren hydropower station may be caused by Huashiban landslide are analyzed which based on predicting the landslide swell height, simulating the water level rising process and evaluating the maximum size of block stone carried by dam breaking flow,the conclusions which according to above analysis will be treated as the basis for feasibility study on decision making of Liangjiaren powerhouse sites selection.A new method of simulating the water level rising process due to the weir dam blocking up a river is proposed on the basis of hydrodynamic numerical simulation which using Delft3D software, as well as the method of estimating the maximum size of block stone carried by dam breaking flow is given, whicb based on applying the theory of riprap grain size for closure by vertical blockade in the field of water conservancy and hydropower project; these methods can be used as a reference to hazard prevention measures and disaster effects analysis of the natural river landslide in deep-cut gorge.关键词
