Webstructure, and soil organic matter are the three main factors which determine the degree of compactness in that soil. (2) Soil compaction has direct effects on soil physical properties such as bulk density, strength, and porosity; therefore, these parameters can be used to quantify the soil compactness. (3) WebSoil compactness of 80 %, 85 % and 90 % were used in laboratory tests, and all the compactness of soil were simulated respectively here. After a lot of trial calculation, when the soil particle porosity in the model is set to 0.28, it is in good agreement with the experimental result of 80 % compaction degree of soil in the test ( Xie et al ...
