TECHNICAL FIELD
[0001] The utility model relates to the field of environmental geotechnical technique especially relates to a high cold region slope vegetation growth simulation and root soil shearing system. BACKGROUND
[0002] As an effective means to improve the stability of the slope, the influence of the root system on the mechanical properties of the soil has gradually attracted attention. In the article "Influence of Root Morphology and Hierarchical Structure on Mechanical Properties of Root-Soil Composite" (Bulletin of Soil and Water Conservation, Vol. 44, No. 2, 2024.03), Xu Hua et al. elucidated the influence of root morphology and hierarchical structure on the mechanical properties of root-soil composite and the mechanism of soil fixation by conducting ryegrass growth parameter testing and direct shear tests. In the article "Analysis of Soil Fixation and Slope Protection Effects of Two Herbaceous Plants on Red Clay Slope" (Chinese Journal of Geotechnical Engineering, Vol. 37, No. 6, 2022.05), Wang Lianrui et al. took the red clay slope as an example, selected Cynodon dactylon and centipede grass as slope protection plants, and obtained that both herbaceous plants have good slope protection effect through planting tests and direct shear tests. Although some achievements have been made in the study of the mechanism of root soil fixation, the research on the mechanical properties of root soil is still lacking, and the existing research on the mechanical properties of root soil only focuses on common environmental conditions, with few studies on the mechanical properties of root soil in high-cold regions.
[0003] In terms of test equipment, the Chinese patent with the authorized publication number CN219961492U discloses an indoor simulation system for plant growth on railway rock slopes in high-cold regions, which includes a rainfall simulation system, a simulation chamber, a sunlight simulation system, and a temperature control simulation system. During operation, it can simulate plant growth environments with different slopes and different environmental characteristics (sunlight, temperature, rainfall conditions, etc.). However, when simulating sunlight, it cannot simulate the changes in sunlight in high-cold regions in real time, and it cannot simultaneously simulate plant growth environments with different slopes during cultivation. Moreover, it cannot perform soil direct shear tests on the original cultivation slope.
[0004] The Chinese patent with the authorized publication number CN107782635B discloses a soil in-situ shear test system, which solves the problem of poor stability during the shear process and the difficulty in providing precise and constant vertical pressure in the field in-situ shear test. However, this system has low automation level and requires multiple manual adjustments for sampling during the experiment, which still causes soil disturbance. When performing shear tests on root-soil composites on different angle slopes, it cannot simulate the growth angle of plant roots, resulting in deviations in the mechanical properties of the root-soil composite.
[0005] In the related experimental research of ecological restoration of rock slope in alpine region, it is an important condition for the success of the experiment to realize the relatively real simulation of the plant growth environment in alpine region and directly test the related mechanical properties. The related experiment of ecological restoration of rock slope in alpine region has low operability, great recovery difficulty, long time consumption and low automation, and the plant growth environment cannot be accurately simulated in the laboratory, especially the simulation of actual plant root growth in different occurrence slopes (different strike, tendency and inclination). Meanwhile, the current direct shear test cannot be carried out in the in-situ environment of plant growth, that is, on the one hand, the disturbance influence caused by sampling in the test process cannot be avoided, and on the other hand, the interweaving relationship between the roots and the soil cannot be embodied in the direct shear test sample, so the alpine region slope vegetation growth simulation and root-planting soil shearing system is proposed to solve the problems in the prior art.
