Problems solved by technology

The traditional centrifugal field rainfall simulation system mainly uses sprinkler water supply to simulate rainfall, but the nozzle simulation is difficult to achieve the uniformity of rainfall on the entire slope. The interference of various factors such as wind speed makes it difficult for rainfall to cover the entire slope

Abstract

The invention provides a rainfall simulation system, comprising a water supply system, a pressure system, a rainfall device and a model box, wherein the water supply system replenishes water for the rainfall device; the pressure system controls the pressure in the rainfall device; the width of the rainfall device is greater than that of the model box; the model box is provided with a side wall cut to be side slope-shaped. The width of the rainfall device is much greater than that of the model box, so that even the rainfall deflection of the rainfall device is relatively large, the side slope surface of the model box can receive the rain completely. The organic glass sidewall of the model box is cut to be side-shaped so as to prevent the blockage for two sidewalls when the rain has inclination in the falling process, thus the surface of the side slope receives the rain uniformly. Furthermore, the U-shaped groove cut on the top inner side of the organic glass sidewall on two sides of the model box leads the fallen rain to flow to the outside of the model box along the groove other than the side slope.

Description

technical field [0001] The invention relates to a rainfall simulation system, in particular to a centrifugal field rainfall simulation system. Background technique [0002] Landslide disasters have the characteristics of high frequency, wide distribution, and serious losses, and they pose serious threats to life and property in many parts of the world. Slope failure may be due to human-induced factors such as too heavily loaded on the slope or cutting of the toe due to construction activity, but the root cause of many slope failures is due to rainfall during which surface water enters the The rock and soil mass increases the self-weight of the slope, increases the pore water pressure, and causes the slope in the limit equilibrium state to slide; the rainfall enters the ground from the surface and turns into groundwater, which soaks and softens the sliding surface, reducing the shear resistance of the slope. Strength: The repeated changes of dryness and wetness of the slope ...
