Experimental Comparative Study On The Different Characteristics Of The Landslide Surge In Mountain Bend River Type Reservoir

This paper is based on the project of Wanzhou port Gangnam Tuokou container terminal in the Three Gorges Reservoir area.Simulating concave reservoir landslide in the laboratory on the basis of investigation and statistics of landslide data in the Three Gorges Reservoir area.Studying on the initial surge,respectively along the swell,swell attenuation,climb higher by numerical calculation and theoretical analysis of the combination of technology and fitting the corresponding empirical formula.Comparing the characteristics of landslide surge in concave bank and convex bank.then identifying the similarities and differences.The main results obtained in this paper are:1.The characteristics of the landslide which has occurred has been counted on the basis of investigation and statistics of landslide data in the Three Gorges Reservoir area.Study on related surge characteristics by the landslide physical model test of the reservoir bank based on these characteristics.2.The basic features of the initial surge and the along swell were analyzed on concave bank landslide.Primary and secondary relationships of factors was obtained by the swell mathematical induction and analysis about the affecting factors.Empirical formula of the initial surge height is obtained.by non dimensional regression analysis method3.The reservoir area is divided into four regions when studying on the attenuation of landslide surge at the concave bank and the empirical formula of those four regions on swell wave height was given.4.The influence of the concave bank landslide surge in action reservoir climb main features and various factors,the formula gives the maximum climb under the surge effect.5.The concave and convex on both sides of the physical model of landslide,the initial surge,along swell,swell decay,climbing and other aspects were compared to identify the similarities and differences between them.The first wave height of convex landslide found from the first wave height contrast is greater and more destructive.The most dangerous position found is the other side of the landslide point into the water in contrast in the run-up.
