Abstract EN
In order to investigate the influence of sand particle-size gradation on cyclic and postcyclic shear strength behaviour on sand-geotextile interfaces, a series of monotonic direct shear (MDS), cyclic direct shear (CDS), and postcyclic direct shear (PCDS) tests were performed using a large-scale direct shear apparatus.
The influence of cyclic shear history on the direct shear behaviour of the interface was studied.
The results indicated that cyclic shear stress degradation occurred at the sand-geotextile interface.
Shear volumetric contraction induced by the cyclic direct shear increased with the increase in cycle number.
The lowest final contraction value was observed in discontinuously graded sand.
In the MDS tests, there were great differences in interface shear strength due to the different particle-size gradations, whereas the differences between shear volumes were negligible.
In the PCDS tests, the shear stress-displacement curves exhibited postpeak stress hardening behaviour for different particle-size gradations, and differences in shear volumes were detected.
The well-graded sand-geotextile interface had a higher value of shear stiffness and a higher damping ratio relative to the other interfaces.
Postcyclic shear stress degradation was observed for the discontinuously graded sand-geotextile interface.
