PhD topic - Lateral and Uplift Load Capacity of Single Piles Socketed into Jointed Rock Mass
Supervisors: Dr Asadul Haque and Dr P. G. Ranjith
Industrial Partner: Mr A. Shahinuzzaman (Powerlink Queensland)
Abstract:
Pile foundations are usually the preferred foundation solution for high rise buildings, transmission lines, and bridges as well as many other civil engineering constructions (e.g., off-shore structures). This foundation type offers high load carrying capacity and smaller settlement or deflection compared with shallow foundations. This is particularly the case when the super-structure is subjected to high lateral forces such as wind, ocean waves, earthquakes and even explosion or blasts. Substantial research has been conducted in the past on the performance of laterally loaded piles founded in soils and many field tests have been undertaken.
However, the same cannot be said for socketed piles in a jointed rock mass. The overall strength and the stiffness of a jointed rock mass are highly variable depending on the joint spacing, orientation, joint persistence, and joint characteristics such as water pressure, joint roughness and infill. All these factors may have significant effect on the lateral load capacity of single piles. Therefore, an understanding of laterally loaded pile behaviour in a jointed rock mass is important in designing foundations for critical infrastructure. This research project studies the lateral and uplift capacity of single piles socketed into jointed rock mass. Research in this area has been inadequate with most published methods assume rock as intact, isotropic and homogeneous. The lack of reliable analytical methods for rock design has caused the current state of practice to adopt analytical tools derived from soil mechanics.
This research project aims to develop design charts for lateral and uplift capacity of piles embedded in jointed rock based on non-dimensional relationships between dominant parameters obtained through extensive numerical modelling using 3DEC.
