The article covers the problem of parameters that underlie the choice of mechanical properties of the clay stone used as the foundation material in Perm. The object of this study is the clay stone of the early Permtric modulus, effective cohesion intercept and angle of internal friction constitute tian age. Mechanical properties, including the deformation modulus, oedomehe subjects of the study. The authors enumerate the following tasks:1) description of geological conditions of the two sites of experiments in Perm,2) development of the methodology of identification of strength and deformation properties of the clay stone in the laboratory (oedometry testing and shear box testing of water saturated and water free samples) and on site (cone penetration tests, pressuremeter tests) according to the Russian technical regulations,3) experiments aimed at identification of mechanical properties of the clay stone,4) analysis and comparison of mechanical properties of the clay stone using various methods,5) provision of conclusions and recommendations concerning mechanical properties of upper layers of the clay stone in Perm.A lot of attention is paid to the analysis of results of cone penetration tests, pressuremeter and laboratory tests. The study has revealed a significant effect of test methods on the resulting values of strength and deformation properties of the local clay stone.
