Variation in lateral load capacity of pile embedded near slope with ground inclination and edge distance

摘要

There are many circumstances in which piles have to be provided on slopes. Experimental model tests in the laboratory have been undertaken to investigate the lateral pile response in sloping ground. The paper discusses about the investigation in a series of 22 laboratory tests in dense sand at 72% relative density. The main motive of the study was to examine the effect of slope angle and edge distance on the pile response. Ground slope was varied as 1 V:1.5H, 1V:1.75H and 1 V:2H for sloping ground condition. Pile response was obtained for seven different positions of pile from the crest of the slope for a specified relative density. Then pile response for horizontal ground condition was obtained for quantification of effect of sloping ground. Displacement and bending moments in the pile increased significantly when the ground surface changes from horizontal to slope. An increase in the edge distance from the slope crest causes reduction in the pile displacement and maximum bending moment.
