Study on the Constitutive Model for Jointed Rock Mass
A new elasto-plastic constitutive model for jointed rock mass, which can consider the persistence ratio in different visual angle and anisotropic increase of plastic strain, is proposed. The proposed the yield strength criterion, which is anisotropic, is not only related to friction angle and cohesion of jointed rock masses at the visual angle but also related to the intersection angle between ...
متن کاملLaboratory and Numerical Modelling of a Jointed Rock Mass
Laboratory tests were performed on 54 large size specimens of jointed rock mass under uniaxial loading conditions. Based on this experimental study, a methodology has been suggested to estimate strength and tangent modulus of rock masses through a weakness coefficient. The methodology involves mapping of joints in the field and laboratory testing of intact rock specimens to arrive at rock mass ...

15 صفحه اولA Comparison of Underground Opening Support Design Methods in Jointed Rock Mass (TECHNICAL NOTE)
It is of great importance to consider long-term stability of rock mass around the openings of underground structure, during design, construction and operation of the said structures in rock. In this context, three methods namely, empirical, analytical and numerical have been applied to design and analyze the stability of underground infrastructure at the Siah Bisheh Pumping Storage Hydro-Electr...
متن کاملElastic-plastic Analysis of Jointed Rock Mass Using Meshless Method
Analysis of rock masses with plenty of weakness planes and joints with numerical methods based on meshes encounters difficulties. In the analysis when even only a few meshes are involved, mesh generation can consume more time and effort compared to the construction and solution of the discrete set of equations. Continuous remeshing of the domain in order to avoid the break down of the calculati...
