Description

technical field [0001] The invention relates to the technical field of testing the tensile force of frozen roots, in particular to a simple combined device and method for measuring the tensile force of frozen roots. Background technique [0002] Slopes are the key research objects of road safety and river water and soil conservation. When using the ecological soil-fixing slope protection method, as time goes by, the plants grow and reproduce, the strength of their root system increases, and the ability to resist slope instability and erosion becomes stronger and stronger. Therefore, It has become one of the mainstream slope protection methods at present. [0003] The key protection function of ecological slope protection is the soil-fixing slope protection ability of the root system. The reinforcement and adhesion of the root system will fix the soil on the road or river slope, and play the role of protection and reinforcement. The tensile strength of the root system determ...
