Abstract
This paper deals with the problem of axially symmetric and its use in applications for geotechnical problems. Considered selection of input data for the problem of the expansion of the cylindrical cavity, namely pressure in the cavity. There are many solutions to the problem of expansion of a cylindrical cavity, with the production of various models of soil. This article presents the re-shenie in rigid-plastic formulation, without the use of the relationship between strains and stresses.
Keywords: rigid-plastic model; the pressure in the cavity; the sealed zone; equality pore volumes.
