土的压实过程和结果受到很多因素的影响。其影响因素有内因和外因两种。就内因而言,主要是含水量和土体本身性质。而对同一种土体来说,其含水量则是影响土体压实的决定性因素。1 土体的三个相体土体一般是由土粒、水和空气组成的三相体,它们各有各的特性,相互相约,共同作用于统一的土体之中,从而构成了土的各种物理性质,如渗透性、粘滞性、弹性、塑性、力学性质等等。在三相体中,当土体的饱和度Sr(土中孔隙水的体积与孔
The soil compaction process and results are influenced by many factors. Its influencing factors are internal and external factors. Internally, the main is the water content and the nature of the soil itself. For the same kind of soil, its moisture content is the decisive factor that affects soil compaction. 1 soil three phase body Soil is generally composed of soil particles, water and air of the three-phase body, each with their own characteristics, mutual co-operation in a unified soil, which constitutes the soil Various physical properties, such as permeability, viscosity, elasticity, plasticity, mechanical properties and more. In the three-phase body, when the soil saturation Sr (soil pore water volume and porosity
