Single and Group Static Laterally Loaded Vertical Pile in Horizontal and Sloping Ground—A Review

Abstract An experimental study was carried out to understand the behaviour of a laterally loaded single pile on a slope with different length/diameter (L/D) ratios driven into cohesionless soil for a relative density of 70%. Static loading was applied in both forward and reverse directions for slopes of 1V:1.5H, 1V:2H, and 1V:2.5H for a constant L/D ratio representing flexible pile behaviour. It was observed that the load ratio (load on a sandy slope to the horizontal ground) decreased with an increase in the slope’s angle. The post-static behaviour of the pile under the same conditions was also studied to evaluate the elastic displacement, which increased with an increase in the slope’s angle. Due to the constant passive resistance under the reverse loading, the lateral load on the slope’s crest was almost equal to the horizontal ground’s condition. The effect of the L/D ratio was studied by varying the length and diameter and by maintaining the other parameter as a constant. The lateral load of a pile increased with an increase in its length and diameter.

Numerical modelling is an efficient method to investigate the effects of the distance from pile centreline to pile centreline on the working of laterally loaded piles considering the shear plastic deformations of the ground. The paper presents the research results the effects of piles spacing on the sloping ground including sand and clay layers subjected to horizontal loading according to the finite element method by ABAQUS software. Group of authors simulate the soil-pile interface, capable of incorporating the gapping and sliding in the soil-pile interfaces for both sand and clay layers. The research results are used to predict the lateral load-deformation of piles for different cases and comparison with published research results. On that basis predicting the suitable distance horizontal loading piles that a pile negligible influenced from adjacent pile on a slope. This is a matter of high scientific and practical significance in foundation engineering in general, as well as in calculating pile foundations on a slopes in particular.

AbstractAn experimental study was proposed to understand the behaviour of single pile in sloping ground with various eccentricity. Cohesionless soil was used for conducting experiments with a horizontal ground and with a slope of 1V:2H. With calculated stiffness factor (T) as 92 mm, the eccentricity was varied as 0T, 0.5T and 1T. The lateral capacity of the pile in horizontal and sloping ground condition decreases with increase in eccentricity; the increase in lateral capacity was linear too. The bending moment increases with increase in load; but the depth of maximum bending moment was 0.15 m for 0T and 0.5T of eccentricity. For 1T of eccentricity, the depth of maximum bending moment varied to 0.07 m from the point of load. An equation was proposed to calculate the maximum bending moment of the pile for any eccentricity for a slope of 1V:2H, which is the governing factor for pile designing.
