<p>This paper describes the methods that can be used to optimize the design of tunnels using a combination of reinforcement and support methods. Particular attention is given to tunnels in very weak rock or soil in which large deformations can occur. Two case ...

This paper describes a method that allows direct use of the Generalized Hoek-Brown criterion in Finite Element (FE) Shear Strength Reduction (SSR) analysis of rock slopes. It describes the generation of shear envelopes for the criterion, lowering of the shear ...

This paper examines the application of Finite Element (FE) analysis to the determination of the factor of safety of rock slopes for which strength is modelled by the Generalized Hoek-Brown failure criterion. The paper first outlines the standard shear strength ...

<p>In this paper in order to overcome the difficulty of finding an acceptable equivalent friction angle and cohesive strength for a rock mass the program called "RocLab" is introduced, as a convenient means of solving and plotting the equations of Hoek - Brown ...

<p>Comparison of limit equilibrium slope stability methods with finite element shear strength reduction technique.</p>

<p>In the assessment of slopes, factor of safety values still remain the primary indexes for determining how close or far slopes are from failure. Traditional limit-equilibrium techniques are the most commonly-used analysis methods. Recently, however, the ...

This paper will discuss application of the Shear Strength Reduction (SSR) method, using finite element (FE) analysis, to determine the stability of slopes in blocky/jointed rock masses. It will demonstrate the method's versatility and reliability through analysis ...
