Characterization of Strength and Deformation of Jointed Rock Mass Based on Statistical Analysis
This paper deals with the statistical analysis of the uniaxial compressive strength and of the elastic modulus of jointed rock masses under different confining pressures. Properties of the rock masses with different joint fabric, with and without gouge have been considered in the analysis. A large amount of experimental data of jointed rock masses from the literature has been compiled and used ...
متن کاملDeformation and strength anisotropy of calcareous slates under Brazilian tests
Rock anisotropy plays an important role in engineering behavior of rocks. Slates are anisotropic rocks which have long been used for gable roof, floor tiles, borrow materials, and other purposes. The slates studied in this research are calcareous and have a porphyro-lepidoblastic texture. To determine the role of the anisotropy on the tensile strength and fracture pattern, two variables includi...
متن کاملSimulation Analysis on the Strength and Acoustic Emission Characteristics of Jointed Rock Mass
Original scientific paper To analyse the influence of joint angle, number and spacing on the strength and acoustic emission (AE) characteristics of rock mass, the uniaxial compression model of rock specimens was established using the micro particle flow PFC2D software platform. The intact rock parameters were determined via trial and error, joints with different angles, numbers and spacing were...
متن کاملestimating the deformation modulus of jointed rock mass under multilateral loading condition using analytical methods
rndetermination of rock mass deformation modulus is very important in different projects, especially in civil and mining engineering works. in-situ measurements such as dilatometer, plate load and flat jack methods may be applied to determine the deformation modulus. however, these methods are very expensive and time- consuming. analytical methods are very useful approaches which can also be us...
متن کاملStrength and Deformation Characteristics of Granular Materials under Extremely Low to High Confining Pressures in Triaxial Compression
— The shearing strength and volumetric relationship of granular materials change notably with a variation of confining pressure. In this study the effect confining pressure on the mechanical behavior of granular materials were observed using discrete element method (DEM). The triaxial tests were conducted on seven specimens covering a range from extremely low to high confining pressures. Each i...
