The shear strength of reinforced rock joints
WebJan 31, 2024 · Davies et al. (2000) examined the shear strength of joints filled with ice, and indicated the shear strength of the interface between ice and rock is controlled by the normal stress and temperature: the greater the normal stress and the lower the temperature, the stronger the shear resistance. WebFoundations on Rock differs from the many texts and handbooks on soil foundations in that it focuses on the effect of geology on the stability and settlement of rock foundations. While the intact rock may be strong, defects in the rock such as faults, joints and cavities, and the deterioration of the rock with time, will have a significant ...

WebExisting reinforced concrete (RC) structures in humid regions suffer from deterioration due to the corrosion of ordinary reinforcement bars damaging the whole system. The deterioration of the transverse reinforcement leads to shear failure, which is one of the most dangerous failure modes. Therefore, researchers suggested using fiber-reinforced … WebMay 10, 2015 · Abstract. The determination of rock bolt contribution to reinforced joint shear strength is still a challenge, especially for assessing reinforced rock mass stability. For this purpose, several experimental studies have been performed during the last decades, mostly on small scale rock joint and bolt specimens. However, to accurately assess the …
