Taking the typical curve channels in the Yangtze River Three Gorges Reservoir area as the prototype,we conceptualize it into a model of curve river-type reservoir to simulate the landslide mass in terms of the geometric size of the landslide,the structure of the inner granular structure and the physical indicators.Taking the water depth,angle of slipping surface,thickness and width of the landslide mass,by-water status and the slope of the riverbed at the site where the landslide mass entered the water as the testing parameters,and letting the landslide mass enter the water from the inner bank,we carry out physical model tests to analyze the features of the head wave’s form,determine the head wave height,and explore the distribution of the head wave’s line of crest through the contour map. Following the flow of the wave energy and based on the wave energy theory,we analyze the wave’s kinetic energy,potential energy and work of pressure,and deduce the total wave energy formula theoretically.
