Abstract
The loads on piles are frequently a combination of vertical and horizontal loads resulting in inclined resultant loads. The lateral bearing capacity of piles is infulenced significantly by this inclined loads. So it is necessary to evaluate the passive-earth-pressure of piles considered the friction between the pile surface and the soil for calculating ultimate latelal resistance of piles subjected to inclined loads. Extensive theoretical studies have been carried out on single vertical piles subjected to horizontal loads. However, to date there does not appear to be any theoretical analysis on vertical and batter piles subjected to inclined loading in various soil condition. The first part of this paper deals with the passive-earth-pressure of vertical and batter piles considered the friction between pile surface and soil.
