Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
Based on the study of the equilibrium of the particles of a soil sample subject to certain suction, in the previous chapter it was possible to establish an analytical expression for the value of Bishop´s parameter χ. This parameter can be written as function of the saturated fraction, the unsaturated fraction and the degree of saturation of the unsaturated fraction of the soil. However, the determination of these three parameters cannot be made from current experimental procedures. Therefore, a porous-solid model simulating the structure of the soil is proposed herein and used to determine these parameters. The data required to build the porous-solid model are the void ratio and the grain and pore size distributions.
