The theory of granular mediums in building and problems of its application

Questions of approaches to the solution of granular mediums among foreign and native researchers are considered. First of all there was an objective about applicability of granular environments mechanics for earthwork and underground construction.The review produced in article can be interest for subway builders. Also it can become a basis of more serious research for other types of construction.We analysed a current state of research of mechanics of granular mediums and drew a conclusion: in matter the native science, despite priorities in researches of this direction, lags behind foreign experience and practically doesn't find applications. Considerable part of the scientists, who were occupied in the granular medium, went abroad and now they are demanded. Today, only enthusiasts are occupied in this matter in Russia. We want to revive native school of the granular medium.
