The shear strength of reinforced rock joints
WebSep 1, 1995 · The shear strength of reinforced rock joints The evaluation of the shear strength of rock joints, reinforced by means of steel dowels, by both experimental measurements and numerical modelling with the aim of determining a provisional tool for optimization of dowel design is presented. WebAug 24, 2024 · This study examined the shear behavior of rock joints and proposed an analytical model for estimating the shear strength at rock joints. Numerous experimental tests indicated that the shear behavior at rock joint depends on many factors including the distribution of initial joint asperity, asperity angle and strength, applied normal stress, and ...

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 ... 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 …
WebIn the present research paper, an attempt has been made to evaluate the strength of a passive rock bolt-reinforced jointed rock under confined condition (σ1, vs. σ3 space). NX size cylindrical specimens of a natural rock having a natural joint were selected for the study. Joint orientation (θ°) of the specimens was varied from 0° to 70° with respect to … 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 …
