In light of the inapplicability of common method to get p-y curves near a slope

a series of model tests on lateral static loading is carried out for single flexible piles near a slope. There are totally 11 series tests of different slope angle and distance between slope and pile. The strain curves of pile are fitted with piecewise cubic polynomial

which avoids singular points effectively. p curves and y curves are gained through derivation and integration of strain curves. The load-displacement curves are drawed

and the influence of slope on the distribution of bending moment is analyzed. Existing expression is introduced and revised according to test results to get the ultimate lateral resistance near a slope. Other reseracher’s expression is employed to get the initial stiffness of p-y curves near a slope. The final expression of p-y curves put forward in this paper is approved reasonable by comparison with a typical centrifuge test results.
