Study on quantitative calculation method of strength-deformation parameters of rock and soil of geological disaster

摘要：

The paper briefly presents failure criterion of rock and soil of geological disaster.Estimating parameters of strength and deformation of rock,soil and pile are a necessary work of stability calculation of land slide,deep excavation pit with the retaining structure.In the paper formulae calculating uniaxial tensile and compressive strengths of the retaining structure are derived from coordination condition of deformation,and formulae calculating cohesion and internal friction angle of rock,soil and the retaining structure are derived from four combination conditions of two-dimensional and three-dimensional stresses with failure criteria of Mohr-Coulombs inclined line and Molars parabola,finally error analysis is discussed.The study results have the important theoretical significance and practical value of engineering.
