Load transfer behaviour of super long piles in multi-layer soft soil through field testing and numerical 3D FEM modelling

Soils and Foundations
The load transfer mechanism of pile foundation has received considerable attention over the years, the simultaneous responses that skin friction and base resistances of super-long piles (length L > 60 m) can have in complex soft soil, however, still need

Hollow cylindrical torsional shear test simulating stress history of sand compaction pile work history

Soils and Foundations
The Sand Compaction Pile (SCP) method is a widely utilized ground improvement technology that enhances the density of the ground by constructing sand piles through penetration and repeated withdrawal/re-driving of a casing pipe.

Investigation on foundation pit uplift mechanism and tunnel response induced by deep excavation under complex support system: A case study

Underground Space
Pit excavation work often occurs directly above metro tunnels, causing adverse effects on the underlying existing operational shield tunnel. Current simplified solutions mainly adopt stress release method to reflect excavation of foundation pit, which is

Optimizing DVA placement using evolutionary algorithms for dynamic beam loading

Studia Geotechnica et Mechanica
Danamic vibration absorbers (DVAs) are used to suppress the excessive structural response due to dynamic loading. To maximize their effectiveness, the placement and characteristics of DVAs need to be carefully chosen.
