Study on Mechanical Properties of Remodeling Site Soil in Northwest Henan Province

Abstract

To comprehensively consider the tensile and shear mechanical properties of site soil in Northwest Henan Province, the shear strength and tensile strength of site soil are determined through the triaxial shear test and uniaxial tensile test. Based on the analysis of the experimental data, the hyperbolic strength formula of site soil is deduced, and the strength failure stress of site soil is corrected by using the geometric relation and stress relation. The research results show that the tensile strength which calculated by using the Mohr-Coulomb strength theory is significantly higher than the tensile test value, the established hyperbolic strength formula can comprehensively and reasonably reflect the tensile and shear mechanical properties of site soil.
