Abstract

Optimum dimensioning of bolts or anchors for the reinforcement of slopes in jointed rock masses, requires compatible strength-deformation data, for both the rock joints and the reinforcing elements. Most types of rock joints behave in non- linear fashion and, thus, realistic modelling can have serious implications in the design, both from the economical and the technical standpoints. This paper will present, briefly, the principles of a constitutive model of joint shear behaviour and a method for optimum bolt or anchor design. The implications of non-linear joint behaviour will be demonstrated with numerical examples. Finally, a case study of slope stabilization, in which the method was adopted, will be reported.

Engineering Design of Rock Slope Reinforcement Based on Non-Linear Joint Strength Model

Optimum dimensioning of bolts or anchors for the reinforcement of slopes in jointed rock masses, requires compatible strength-deformation data, for both the rock joints and the reinforcing elements. Most types of rock joints behave in non- linear fashion and, thus, realistic modelling can have serious implications in the design, both from the economical and the technical standpoints. This paper will present, briefly, the principles of a constitutive model of joint shear behaviour and a method for optimum bolt or anchor design. The implications of non-linear joint behaviour will be demonstrated with numerical examples. Finally, a case study of slope stabilization, in which the method was adopted, will be reported.
