摘要：Structures like, bridge abutment on steep river slope, open type berthing structure, electric / telephonepoles on high way/ railway embankment and approach to water intake tower in river /sea are constructed in slopingground and this structures are subjected to lateral load due to the lateral soil movement of unstable slope. Lateralmovement of these unstable slope results in large lateral force on pile supported structures. In order to understand suchtype of behaviour, an experimental investigation is necessary. Due to such lateral loads and the no availability of goodconstruction sites, engineers are often required to place footings at crest or near slopes. Therefore, the footings in thefield generally face large lateral forces and lateral soil movement. These structures may be subjected to large lateralloads, such as violent winds and earthquakes. Widely used types of foundations for these structures are pierfoundations, subjected to lateral loads is similar to that of a short rigid pile, because both elements seem to fail byrotation developing passive resistance on opposite faces above and below the rotation point. This paper describes theresults of several experimental studies performed on laterally loaded and load inclined on long pile located near slopes.Initially, in this paper, the results of tests of single pile subjected to lateral loading, in homogeneous sand with (1V:2H)slope and load with inclination of 15° and 30° were carried out.An extensive program of laboratory model tests was undertaken to study the effect of slope and loading direction onlaterally loaded pile in cohesionless soil. The paper includes studies of the effect of distance from the crest of the slope,direction of loading (angle of inclination with respect to horizontal), soil properties. The pile lateral capacity in slopingground was compared with loading at different angle of inclinations. From the experimental investigation, it isobserved that when piles installed away from the crest of the slope at a distance of 5 times the pile diameter, theinfluence of slope in the lateral-load capacity is almost negligible over inclined loading of 30°.
