Multi-functional experimental device for simulating bevel flowing water force factor and experimental method thereof

Abstract

The invention discloses a multi-functional experimental device for simulating a bevel flowing water force factor and an experimental method thereof. The method comprises the following steps: sorting for selection according to difference of included angles formed by the arrangement direction of through holes and a longitudinal side of a porous plate by adopting a detachably-connected porous plate; selectively independently using buildings or building models with the bottoms provided with a plurality of connecting columns or using the buildings or the building models in a combined manner according to actual conditions of a drainage basin bevel to be simulated, and selectively using different quantities of plastic rods which are combined for use and in a different arrangement manner; during use, respectively inserting the connecting columns and the plastic rods of simulated models into the through holes to form a close fit so as to simulate the distribution conditions of flowing speed, flow rate, water depth and flow speed field of overland runoff under different bevel surface conditions. The device disclosed by the invention is simple in structure, simple and convenient to operate in an experiment process, real and accurate in experiment results and applicable to analysis and research on numerical value measurement and distribution characteristics of hydraulic factors of modern drainage basin bevel flows.

Description

technical field [0001] The invention relates to an experimental device and an experimental method for simulating hydraulic elements of slope flow, in particular to a multifunctional experimental device and an experimental method for simulating hydraulic elements of slope flow, and belongs to the technical field of watershed hydrological process simulation. Background technique [0002] Due to the impact of human activities such as urbanization, agricultural cultivation, and grass planting, human disturbance has been caused to the slope of the watershed, which has a strong impact on the formation of slope flow and the process of confluence, and the response relationship between rainfall and slope runoff has become abnormal. , disastrous rainstorms and floods occur frequently, and often lead to hydrogeological disasters, which are the main characteristics of modern watersheds. [0003] At present, the torrential rain, flood disasters and hydrogeological disasters that occur ev...

AI Technical Summary

Problems solved by technology

[0007] In the existing various types of indoor water tank experiments, most of the simulation of slope conditions is to lay sand, stones, vegetation, etc. at the bottom of the tank. Although this experimental method can prove to a certain extent that different slope conditions have an impact on surface water flow, However, under the influence of human beings, the influence of regularly arranged farmland, turf, roads, etc. on the slope surface on the hydraulic elements of the slope cannot be simulated, because when the runoff flows from different directions on the regularly arranged modern watershed, its hydraulic elements will occur. However, there is currently no experimental device to study and simulate this, and when the experiment is carried out in the existing experimental tank, due to the scouring and carrying capacity of the water flow, some of the sand and stones laid on the bottom of the tank will be carried along with the erosion of the water flow out of the water tank, thus causing distortion and error in the simulation results

[0008] Therefore, in the current indoor simulation experiments, it is difficult to describe the change mechanism of the hydraulic elements of the slope flow in the modern watershed comprehensively and accurately through calculation or using text, and it is necessary to supplement the experimental model for relevant simulation experiments
