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 multiple simulation factors (such as Chinese patents CN 103792333 B, CN 203705436 U, etc.)

Description

Technical field [0001] The invention belongs to the technical field of rock and soil quality engineering, and relates to a new type of test instrument for studying soil disintegration characteristics and evaluating soil water and soil conservation ability, in particular to a multifunctional soil disintegration test device. Background technique [0002] Soil disintegration is the phenomenon that the soil body breaks down, collapses, or weakens after soaking (Loess Plateau Soil Erosion and Management Mode [M]. Jiang Dingsheng. Beijing: China Water Power Press, 1997: 60), and its mechanism may be Because water molecules enter the voids of the soil to squeeze the gas, the internal stress is concentrated, so that the repulsive force of the soil exceeds the suction force, causing the soil to collapse and collapse (Experimental research on the collapse characteristics of reshaped loess[J].Gao Jianwei, Yu Hongming, Qian Yuzhi , Li Ke. Journal of Yangtze River Scientific Research Institut...
