Bed load grading determination method and device, storage medium and electronic equipment

Abstract

The invention relates to the field of sediment model tests, in particular to a bed load grading determination method and device and electronic equipment.The method comprises the steps that a sediment adding test model is established according to a to-be-tested water area to ensure that the environment of the to-be-tested water area is simulated, and meanwhile water area parameters of the to-be-tested water area are obtained; sand adding gradation is determined according to the water area parameters; sand adding is conducted on the bed load in the sand adding test model according to the sand adding grade, and the bed load after sand adding is obtained; the bed load after the sand is added is sampled so as to obtain the sampling gradation of the bed load after the sand is added; the bed load gradation corresponding to the water area to be tested is accurately determined according to the sampling gradation and the sand adding gradation, and then it is guaranteed that the sand adding test model can accurately simulate the water area to be tested.

Description

technical field [0001] The present application relates to the technical field of sediment model testing, and in particular to a method for determining the gradation of a mass, a storage medium, and an electronic device. Background technique [0002] In some mountainous waters, soil erosion is serious, landslides and mud-rock flows occur frequently, and the amount of moving sand is large. After the moving matter deposits, it will cause various hazards, such as reducing the effective storage capacity, affecting the comprehensive benefits of cascade hydropower stations, raising the tail water level of the reservoir, reducing Upstream cascade power generation head. In the later period when the drift mass is silted in the reservoir, once the drift mass crosses the dam, it will cause damage to the discharge structures and generating units, and affect the safety of the wading structures. It can be seen that the flow quality has become one of the key issues in the development and o...

AI Technical Summary

Problems solved by technology

But at present, the saturated sediment delivery rate and bed sand gradation of the experimental river section are generally used as the sand addition rate and sand addition gradation in the mass flow test. However, the law of mass movement is affected by factors such as the bed sand gradation, incoming water and sand flow conditions, etc. There is a complex response relationship between the parameters, and the traditional method cannot guarantee the accuracy of the mass gradation, which leads to the inability of the experimental model to accurately simulate the experimental river section
