The implementation of the technique opens wide possibilities in rock mechanics and rock engineering, because continuously measured thermal...

... are investigated. Unconfined compressive strength tests (UCS) on limestone specimens were performed to determine the peak strength and crack initiation threshold. Additionally, the deformation characteristics were determined. Mineralogical analyses including X-Ray Diffraction were performed on each specimen. Micro...

... ABSTRACT: Weathering has several effects on the physical, strength and material behaviour characteristics of rocks. Various researchers have attempted to obtain weathering classifications using qualitative and/or quantitative approaches. In this study, material behaviour under uniaxial loading...

..., characteristics and design of any type of cavern closely depends upon the final requirements for its use. 1 INTRODUCTION Hydroelectric power houses and crude oil storage cavities are the two major types of large underground caverns. This paper exposes the deep differences that actually exist between the two...

... ABSTRACT: The fractures geometrical characteristics can be calculated by various sampling methods in 1 dimension (1D) & 2 dimensions (2D). The Discrete Fracture Network (DFN) simulation results show some of the equations are suitable for calculation of mean trace length and the difference...

... of the numerical analysis is consistent with that tendency. Furthermore, we also propose a conceptual model of the EDZ showing the extent, hydraulic and mechanical properties of rock mass, and the characteristics of the fractures from the results of this research and previous studies. 1 INTRODUCTION Effective...
