Abstract:
An experimental program is carefully planned and executed to understand the phenomena of soil–pile system to combined uplift and lateral loading in sand. Aluminium model piles with different L/D ratio, made up of 25.4 mm outer and 19.0 mm inner diameter and model steel test tank with dimensions of 1.0 m × 1.0 m × 1.2 m (depth) is used to avoid boundary effects in testing. Tests were conducted to measure pile behavior under independent uplift, lateral loadings and lateral load tests by keeping the constant uplift load of 40{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465}, 60{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} and 80{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} of ultimate load on pile head. It is observed that there is significant variation in lateral load-pile head deflection behavior as well as the ultimate lateral capacity under combined loading compared to independent loading.
