Abstract

The present invention relates to the technical field of soil and water characteristics, in particular to a device and method for measuring soil moisture characteristic curves under alternating dry and wet conditions based on a salt solution method, including a base, a connection box is fixedly installed on the upper end of the base, and the upper end of the connection box is A box body is movable installed, and the inner top surface of the box body is movably installed with a soil tank through a lifting mechanism, and a number of chutes are provided on the upper end surface of the base, and a number of storage tanks are slidingly inserted in each of the chutes. The number of the storage cells is several and arranged in an array. The storage cells located at the front and rear respectively move through the front and rear end faces of the connection box. The present invention can replace different saturated salt solutions, and can carry out different times of The dry-wet cycle can also perform dry-wet cycles with different intensities, and can also measure the soil-water characteristic curve of soil samples before and after the dry-wet cycle treatment. The device has multiple uses and is easy to operate.

Description

technical field [0001] The invention relates to the technical field of water and soil characteristics, in particular to a device and a method for measuring soil moisture characteristic curves under alternating wet and dry conditions based on a salt solution method. Background technique [0002] Due to global climate change, drought and flood disasters occur frequently, and the phenomenon of soil cracking is becoming more and more common. Under the condition of natural rainfall and evaporation, the soil undergoes repeated cycles of drying and wetting. During this process, the volume of the soil will expand and shrink, which will further change the permeability, water and solute migration laws, cause irreversible deterioration and attenuation of the soil structure and strength, and then lead to instability such as landslides, slips, collapses, and collapses. The occurrence of the phenomenon will lead to the occurrence of disasters, and it will also have a great impact on engi...
