Shear strength of rock joints influenced by compacted infill

Shear Strength of Rock Joints Based on Quantified Surface Description

One of the primary objectives of this work is to better understand the frictional behavior of joints under shear loads, including the creation of damage zones. Discontinuities have an important influence on the deformational behavior of rock systems. The choice of a general criterion to determine the shear strength of rough rock joints is a general problem that has been investigated for many ye...

Shear Strength of Unfilled and Rough Rock Joints in Sliding Stability Analyses of Concrete Dams

Laboratory Study of the Shear Behaviour of Natural Rough Rock Joints Infilled by Different Soils

Natural rock joints infilled with soil materials may show a reduced shear strength, which influences rock mass stability. The aim of this paper is to experimentally investigate the shear behaviour of infilled rock joints, taking into account joint surface characteristics and the properties of the joint and infill materials. A new model for predicting the shear strength of infilled joints is pre...

Study on the shear strength degradation of ACA joints induced by different hygrothermal aging conditions

Article history: Received 13 June 2012 Received in revised form 1 June 2013 Accepted 15 June 2013 Available online 17 July 2013 The effect of the different hygrothermal conditions on the shear strength degradation of ACA joints and the difference among them are studied in this paper using experiments and numerical simulations. First of all, several hygrothermal aging tests with different accele...

Shear Bond Strength of Denture Repair with Autopolymerizing Acrylic Resin Influenced by Three Surface Treatments

The repaired denture base material fractures at the interface of base and repair material. This study evaluated the effect of different chemical treatment of the surfaces on the shear bond strength of conventional heat-cured resin repaired with autopolymerized acrylic resin. The specimens were divided into four groups, 30 specimens each according to surface treatment by chemical etchants Group ...
