Investigating Mechanical Properties of Argillaceous Grounds in Order to Improve Safety of Development of Megalopolis Underground Space

摘要

This article discusses strength and deformation properties of argillaceous formations in megalopolis underground space. It is established that they are characterized by anisotropy of mechanical properties, which is directly related with the processes of generation of soil bodies. Rather frequently layered grounds are considered as transversal isotropic medium, the strength and deformation properties of which depends on direction of load application with regard to the stratification plane. On the basis of laboratory tests the values of strength and deformation properties have been obtained which could be used as parameters of transversal isotropic medium for mathematical and numerical simulation.
