Finite element prediction on the response of non-uniformly arranged pile groups considering progressive failure of pile-soil system
A uniform arrangement of individual piles is commonly adopted in the conventional pile group foundation, and basin-shaped settlement is often observed in practice. Large differential settlement of pile groups ...
