Investigation of group effect of large pile groups under lateral loading

At present, the understating of the lateral behavior of large pile group foundations (> 100 piles) supporting bridges, high-rise buildings, marine structures, and LNG tanks is limited. There are no definitive published design recommendations or guidance on evaluation of the lateral group effect of large pile groups. The current design standards (e.g., AASHTO, Canadian Foundation Engineering Manual) are based on the previous experimental results of full-scale and model testing of much smaller pile groups (< 25 piles). Therefore, a great uncertainty lies in extrapolating the recommendations of the group effect for the small pile groups to the design of much larger pile groups. The appropriateness of such extrapolation remains a subject for investigation. This project aims to develop analytical and numerical solutions for this investigation. The outcomes of this research will enhance the partner company’s capability in designing large pile groups under lateral loading and safeguard the infrastructure in Canada.
