Problems solved by technology
[0002] At present, the method for comprehensively evaluating the anti-corrosion properties of soil is not complete, and the surface erosion (erosion mentioned in this patent refers to loss erosion and wind erosion) tests are mostly carried out directly on the spot or in the establishment of large-scale models, and the investment is relatively large, and It is difficult to evaluate the anti-erosion characteristics of the soil inside and outside at the same time
The known methods for evaluating the anti-erosion properties of soil are generally on-site or model tests, or only internal erosion tests, and it is difficult to comprehensively evaluate the anti-corrosion properties of the soil surface and interior in the case of coupled erosion

Embodiment Construction
[0026] The present invention will be further explained below in conjunction with specific embodiments and the drawings in the specification.
[0027] See figure 1 , The present invention includes the following steps:
[0028] 1) Select and make soil samples. Choose undisturbed soil or disturbed soil. The disturbed soil is pre-embedded with several steel wires at equal intervals during sample preparation. After the sample preparation is completed, the steel wires are drawn out to form several axial directions along the soil sample. The undisturbed soil is perforated with steel needles at equal intervals during sample preparation, and a number of holes along the axial direction of the soil sample are formed inside the soil sample; the diameter of the holes is 1mm, and the soil sample is made into a cylindrical or rectangular shape;
[0029] 2) Place the soil sample in a transparent tempered glass or tempered plastic container corresponding to the size of the soil sample, use airflow or...

Abstract
The invention discloses a test method for comprehensive assessment of soil anti-erodibility. The invention is aimed at evaluating anti-erodibility of soil under the effects of surface erosion, internal erosion and coupling erosion, and the method employs a technical scheme, which comprises the following steps: 1) selecting and making a soil sample, and arranging several holes at the axial direction of the soil sample in the soil sample; 2) eroding surfaces of the soil sample with air-flow or water-flow, and recording mass of the soil which is eroded; 3) introducing air-flow or water-flow into holes in the soil sample, eroding the internal part of the soil sample, and recording mass of the soil which is eroded; 4) cutting the soil sample at the radial direction, measuring dimension of the holes which are eroded in the soil sample, and recording dimension changes of the holes; 5) completing the evaluation of the anti-erodibility of soil according to the mass of the soil which is eroded on the surface of the soil sample, the mass of the soil which is eroded in the soil sample, and dimension changes of the holes in the soil sample.
Description
Technical field [0001] The invention relates to the field of soil anti-corrosion testing, in particular a test method for comprehensively evaluating soil anti-corrosion. Background technique [0002] At present, the methods for comprehensively evaluating soil anti-corrosion properties are not complete. Surface erosion (the erosion mentioned in this patent refers specifically to erosion erosion and wind erosion) tests are mostly carried out directly on site or building large-scale models, with a lot of investment, and It is difficult to evaluate the anti-erosion properties of the soil inside and outside at the same time. Known methods for evaluating soil erosion resistance are generally on-site or model tests, or only internal erosion tests. It is difficult to comprehensively evaluate the soil erosion resistance characteristics of the soil surface and the interior under coupled erosion conditions. Summary of the invention [0003] In order to solve the problems in the prior art, t...
