In this paper, a new approach based on the demand-capacity model is developed for hydraulic design of granular and granular-cum-geocomposite drainage layers in pavements. The demand is given by the intensity-duration curve obtained from the Intensity-Duration-Frequency curve, which is geographic location specific and corrected for climate change. The capacity curve corresponds to critical infiltration

Morphological insights into the liquefaction and post-liquefaction response of sands with geotextile inclusions using drained constant volume simple shear tests Geotext. Geomembr. (IF 5.2) Pub Date : 2023-06-16 Balaji Lakkimsetti, Gali Madhavi Latha
The present study aims to explore and bring out morphological insights into the prior-liquefaction, liquefaction, and post-liquefaction response of sands with geotextile inclusions. For this, a series of multi-stage drained constant volume simple shear tests with different cyclic stress ratios (CSR ranging from 0.1125 to 0.225) and different frequencies (f of 0.2 and 1.0 Hz) were carried out on completely
