Constitutive model and elastic parameters for layered rock mass based on combined Hooke spring

Constitutive model and elastic parameters for layered rock mass based on combined Hooke spring Layered rock mass has special geologic mechanical properties. The constitutive relationship and elastic parameters play an important role in engineering design and analysis. In this paper, the constitutive relation and elastic parameters calculation model are proposed for the parallel, vertical and inclined layered rock mass with combined Hooke spring model and coordinate transformation method. The sensitivity factors and regularity effect on the mechanical parameters are analyzed with single factor analysis method. The results show that the elastic parameters of layered rock mass are controlled by thickness, elastic parameters and inclined angle of the bedding plane and interlayered rock. Comparing the elastic Modulus of calculation and simulation, the errors are respectively in 0.23%–3.75% and 1.17%–2.87% for vertical and parallel direction. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Strength, Fracture and Complexity iospress

Abstract

Layered rock mass has special geologic mechanical properties. The constitutive relationship and elastic parameters play an important role in engineering design and analysis. In this paper, the constitutive relation and elastic parameters calculation model are proposed for the parallel, vertical and inclined layered rock mass with combined Hooke spring model and coordinate transformation method. The sensitivity factors and regularity effect on the mechanical parameters are analyzed with single factor analysis method. The results show that the elastic parameters of layered rock mass are controlled by thickness, elastic parameters and inclined angle of the bedding plane and interlayered rock. Comparing the elastic Modulus of calculation and simulation, the errors are respectively in 0.23%–3.75% and 1.17%–2.87% for vertical and parallel direction.
