Description

technical field

[0001] The invention relates to the technical field of soil porosity detection, in particular to an automatic operation platform for quickly analyzing soil porosity at different depths. Background technique

[0002] The freeze-thaw cycle is the process of continuous freezing and thawing of the soil, which redistributes the water in the soil and weakens the structure, and changes the original skeleton and fabric of the soil, which are closely related to the porosity of the soil. Relationship. It is determined by experiments that with the increase of freeze-thaw times, the porosity of the original loess fluctuates between 0.325-0.426, while the porosity of the remodeled loess fluctuates between 0.348-0.433. plastic loess.

[0003] Especially in the Qinghai-Tibet Plateau region, the freeze-thaw cycle has great significance for the change law of soil porosity. Under the continuous freeze-thaw cycle, the soil porosity changes repeatedly and unevenly. Most of th...
