Abstract

The invention belongs to the field of water conservation projects, and provides a model platform for slide surge tests and a method for researching original waves. Laboratory simulation technology for slide surge is realized on the premise that substance composition of a sliding mass and a movement state of the sliding mass are taken into consideration, source data induced by an acquisition transducer of a data acquisition instrument are utilized, a wave time domain graph is drawn, period of the original waves is obtained via the wave time domain graph by the aid of a zero method and a peak and valley method, the wave height of the original waves is obtained by the peak and valley method, a dispersion equation of the waves is iterated by a bisection method, the wavelength of the original waves is obtained, three elements of the original waves of slide surge are accurately obtained, the model platform is reasonable in designed, and theoretical foundation and scientific evidence are provided for further research of characteristics and propagation rules of slide surge.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering, in particular to a model platform for landslide surge tests and a method for studying original waves. Background technique [0002] In water conservancy projects, landslides on the shore of reservoirs occur from time to time, and the surges caused by landslides in the reservoir may cause major geological disasters to water conservancy facilities, port and waterway projects, and people's lives and properties in nearby areas. Large-scale landslides can generate huge surges. These surges not only cause immediate harm to everything that affects the waters at any time, but more importantly, with the propagation and superposition of surges, it is possible to cause reservoir accidents such as dam breaks and embankment bursts. Accidents and channel blockage, ship capsizing and other general accidents. [0003] After the reservoir is impounded, due to the high water level of the reservoir and...
