Problems solved by technology

[0003] At present, there are many types of soil disintegration experimental devices commonly used, but most of them have single functions, the disintegration surface is inconsistent with the disintegration surface in the real environment, and the simulation of conditions such as dry and wet cycles is also inconsistent with the reality. Water pressure conditions, slope conditions, water immersion conditions, water erosion and other single or compound conditions, respectively, test the impact of soil disintegration characteristics, and it is impossible to use the same experimental device for the same test soil to achieve water pressure conditions, slope conditions, Under water immersion conditions, water flow erosion and other simulation factors are switched to test the disintegration characteristics of the soil under the switching of various simulation factors

Description

technical field [0001] The invention belongs to the technical field of rock and soil geological engineering, and relates to a novel test instrument for studying soil disintegration characteristics and evaluating soil water and soil retention capacity, in particular to a multifunctional soil disintegration experimental device. Background technique [0002] Soil disintegration is the phenomenon that soil collapses, collapses, or weakens after soaking. The mechanism may be that water molecules enter the soil voids to squeeze gas, and the internal stress is concentrated, making the repulsion of the soil itself exceed the suction, resulting in soil collapse. The body crumbles and disintegrates. Soil disintegration mechanism is closely related to the occurrence process of soil erosion, is one of the necessary conditions for soil erosion to occur, and is an important soil physical index for evaluating the severity of soil erosion and soil erosion. The evaluation of soil disintegra...
