[Abstract]:In this paper, the characteristics of landslide surge in the three Gorges Reservoir area are studied, which provides a solid foundation for the establishment of a sound evaluation system for the influence of landslide surge on navigation channel. Based on the investigation and classification of landslide data in the three Gorges Reservoir area, aiming at the problems of surge caused by soil landslide, rock mass landslide and steep rock mass landslide in the reservoir area, through model test and theoretical analysis, the initial surge is systematically and completely analyzed. The basic characteristics of inrush along the course, the attenuation of surge and the climb are studied, the corresponding empirical formulas are fitted out, and a simple engineering example is given to verify the characteristics of the surge. The main research results are as follows: (1) based on the investigation and data analysis of the landslide in the three Gorges Reservoir area, the characteristics of landslide in the reservoir area are summarized. According to the characteristics of the landslide of large and medium rock mass, steep rock mass and soil landslide, the physical model test of landslide surge and the analysis of related surge characteristics are carried out in the bend and straight flume respectively. (2) the basic characteristics of the three types of landslide surge are analyzed, the influencing factors are summarized and analyzed mathematically, the primary and secondary relationships of the influencing factors are obtained, and the method of dimensionless regression analysis is used to analyze the primary and secondary characteristics of the three types of landslide surges. An empirical formula for calculating the initial surge height is established. (3) the landslide surge of rock mass is obtained by using multiple linear regression analysis. The attenuation characteristics of wave height and the corresponding formula of wave height attenuation coefficient of steep rock mass landslide surge wave and soil landslide surge wave are analyzed. (4) the main characteristics and the influence of various factors on the reservoir shore height under the action of rock landslide surge wave are analyzed. The empirical formula of maximum climbing under the action of surge wave, the calculation formula of soil mass and rock mass landslide, (5) combining with the landslide of Dayantang rock mass in Qingjiang River, the landslide of Jizaizi soil of the Yangtze River, are given. The three types of landslides in Lianziya steep rock mass of the Yangtze River are calculated and verified by the calculation of the initial surge height and climbing height. The results are basically consistent and can be applied to relevant projects.
