Load–deflection analysis of laterally loaded piles in unsaturated soils

M Ghazavi, E Mahmoodi, H El Naggar - Acta Geotechnica, 2023 - Springer
The lateral response of piles is governed by the soil–pile interaction in the shallower layer of
surrounding soil, which may be above the water level and thus is unsaturated. There is no …
