There have been many theories and interpretations of the compression process for soil. However due to the complexity of the compression process for a wide range of soil states, i.e., suspended, liquid, plastic, semisolid or solid states like rock, the interaction between the states or the transition from one state to another, there have often been misunderstandings and difficulties regarding the application of these theories. In this study, an ideal particle distribution in an ideal ground system is derived to find the equation of state, a general compression process for a wide variety of soil types and states. In other words, it is a general relationship between the void ratio and effective overburden pressure in terms of interparticle energy and is thus a “law of soil.” The principle is based on the law of energy distribution in statistical mechanics. The derived equations can be applied to describe the void ratio profile and the compression process of various soils. Case studies show that this theoretical approach agrees well with the experimental data obtained for several soils such as sediments, Mexican City clay, sand and others.
