Pollutant transport and performance evaluation in defective composite cutoff walls: centrifuge test and numerical simulation

Soils and Foundations
The composite geomembrane-soil-bentonite (CGSB) cutoff wall is one of the most effective barriers to prevent pollutant transport in groundwater. However, geomembranes may have defects during construction, significantly increasing the risk of pollutant ...

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
