Abstract

the purpose of this study is presenting and study of simple equations to estimate the uniaxial compressive strength of marly limestone of Abderaz formation. Many engineering structures such as dam, tunnel and road have been constructed on this formation in the northern part of Khorasan Razavi province. For determation physical parameters and uniaxial compressive strength of marly limestone, 39 samples according to the International Society of Rock Mechanics Standards (1981) of Abderaz formation were collected. Physical properties which determined including of porosity, density, water absorption. Results which obtained from the simple regression method, indicating a better relationship between density and uniaxial compressive strength in comparison with the other physical properties. The best multivariate correlation is obtained between uniaxial compressive strength with density and water absorption.
