Mined. In practice, there are the following problems: 1. For the soil sample collection of artificial excavation profiles, the sampling depth is generally controlled more accurately, but the labor is intensive, and the excavation profile has a huge disturbance to the surface, which is easy to damage the surface vegetation and cause water and soil. 2. A small number of samplers will compact the soil sample due to the vertical external force, which will affect the physical properties of the soil sample, especially the porosity, which will adversely affect the subsequent experimental analysis.
