Деформационная анизотропия известняка-ракушечника Одесского региона

Abstract

Anisotropy coefficients were Determined during field tests of limestone-shell rock along and across the stratification. It is established that the mechanical characteristics of limestone shell rock largely depends on their anisotropic properties, which must be taken into account in the calculation and design of foundations. The anisotropy coefficient in determining the compression resistance at deformations of 0.4 – 0.8 mm is 1.6, and the deformation modulus within the pressures of 0.4 – 1.0 MPa in the air-dry state is 123 MPa across the lamination, and along the lamination – 308 MPa.
