Description

technical field [0001] The invention relates to the technical field of degradation test simulation, and more specifically, the invention relates to an intelligent test device for simulating degradation of rock and soil mass and a simulation method thereof. Background technique [0002] At present, with the development of new technologies and the continuous development of interdisciplinary subjects, laboratory test chambers have also been vigorously developed. At present, the test chambers commonly used in laboratories include drying ovens, biochemical incubators, mold incubators, etc. The drying ovens are mainly used for drying test samples. The dehydration process is carried out under certain temperature conditions. The internal structure is mainly composed of heating furnace wire, intelligent switch and blower motor, etc., which has a wide range of applications in geotechnical engineering tests.

AI Technical Summary

Problems solved by technology

[0006] The temperature control in the existing test chamber, whether it is the temperature control of the electric heating furnace wire and the blower motor or the temperature control of the air compressor, the temperature set by the two temperature control systems can only reflect the artificially set temperature in the test chamber, not It can simulate the temperature change caused by the change of sunlight intensity in the natural environment. The sunlight intensity is mainly reflected by the index of total sunlight radiation; the humidity control is mainly carried out by atomizing liquid water in the form of a humidifier. , the device cannot reflect the change of humidity on the surface of rock and soil in nature due to the change of humidity before and after rainfall. During the rainfall, water is directly sprayed on the surface of rock and soil, and the atomized water vapor generated by the humidifier can only reflect the change of humidity in the environment, but cannot reflect the humidity of the water. The process of spraying on the surface of rock and soil, in addition, there is a kind of splashing effect of rainwater on the surface of rock and soil during rainfall, which cannot be simulated by the existing technology;

[0007] The light source provided in the existing test box is relatively simple, the mold incubator can only provide ultraviolet light source, and the upgraded version of the incubator can only provide incandescent light source, and the cost of the test box is often very high. The light source cannot be switched, the light source is relatively single, and the above two existing light sources cannot simulate the impact of changes in the intensity of sunlight in nature on the degradation of rock and soil
