The load test was performed for drilled shaft with rock-socket which was located under a bridge pier. A Hoek-Brown failure criterion, able to consider non-linear strength behavior of rock, was selected for constitutive model of rock. The calibrated model has been selected for parametric study....
According to Sagong and Paik (2003), the side resistance of rock socketed drilled shafts is affected by rock quality, types, uniaxial compressive strength, and confining stress. Their approach based upon the Hoek-Brown criterion provides reasonable predictions of the side resistance. In this study...
Rock-socketed filling piles have been widely used especially in bridge engineering due to its advantages.But when the covering subsoil is weak or the unsupported pile top part is long,the buckling failure of the pile shaft should be regarded as a problem.To investigate the influence of the co...

Engagement of the rock bolt drive head 102 in the bolt drive socket 18 is best depicted in the cross sectional view of Figure 4. Whilst a drive head and socket arrangement is depicted, any other suitable form of rotational driving engagement between the shaft and rock bolt may be utilised ...
This paper presents a shear load transfer function and an analytical method for estimating the load transfer characteristics of rock-socketed drilled shaft
a differential equation of load transfer for rock-socketed piles (RSPs) considering RF was formulated by applying the Runge‒Kutta method. Considering RF, the pile top load versus settlement curves and the pile–rock relative displacement (sp‒r) versus pile side friction (τp‒r) curves ...
