Fictitious pile method for fixed-head pile groups with dissimilar piles subjected to horizontal loading

Soils and Foundations, 2022
Pile groups are traditionally designed with similar piles in length, diameter, and property. However dissimilar piles may occur in the cases of foundation reuse and economical building design.

Cyclic Degradation Parameters of Flow-Controlled Geomaterial for Pile Group Subjected to Torsional Loads

Applied Sciences, 2023
The pile groups support large foundation structures which often experience cyclic torsional loads. Several theoretical and experimental investigations were carried out on pile groups under axial and lateral cyclic loads; however, the study of the ...

Comparative Experimental Study on Bearing Capacity of Roof Beneath Single Piles and Pile Groups in Karst Area

Buildings
By designing and conducting indoor model tests on single piles and 2 × 2 pile groups under four working conditions—underlying cave, overlying cave, pile penetrating underlying cave, and beaded caves—the failure mode of the roof was explored, and its ...

An Analytical Method Evaluating the Evolution of Group Effect for Vertically Loaded Pile Groups Subjected to Tunnel Excavation

Applied Sciences, 2022
Tunnel excavations near existing vertically loaded pile groups are frequently encountered in urban areas, and most available studies have focused on the additional deformation and stress induced in the pile group, lacking in consideration of the ...

Vertical dynamic impedance of pile groups considering topographic effects

Yantu gongcheng xuebao
In this study, the theoretical equations for vertical impedance for single piles are deduced based on the Hamilton's principle. The reasonable method for calculating the pile-to-pile interaction is proposed considering the vibration difference with ...

Response of group piles subjected to coupled vertical-eccentric lateral-seismic loads

Results in Engineering
In seismic prone regions, analyzing loaded pile groups can be challenging because of limitations in conventional design methods and the inability of small-scale laboratory tests to accurately replicate the real behavior.

Static pile-soil-pile interaction in offshore pile groups

, 2016
This thesis is a theoretical study, using both finite element and boundary element methods, of the behaviour of single-piles and pile groups under vertical and lateral loading. It offers an improved understanding of the soil-structure interaction that occurs in pile groups, particularly closely spaced piles subjected to lateral loads.
