“…3 was suggested and was found to have advantages over p-y curve method [3,45]. SW model analysis predicts the response of LLPs and had shown very good agreement with actual field tests in sand, clay and layered soils.…”

“…It was observed in the study that the nonlinearity of the soil is found to increase the top displacement of the pile group and decrease the fixed moments and positive moments. Kim et al have conducted studies on pile-soil system subjected to lateral loads in clay soil by improved wedge failure model and hyperbolic p-y criteria [45]. The proposed p-y curves with an improved wedge model are more appropriate and realistic for representing a pile-soil interaction for LLP in clay than the existing p-y method.…”

Soil-structure interaction plays an important role in the behavior of structure under static or dynamic loading. It influences the behavior of soil, as well as the response of pile under loading. The analysis is highly essential for predicting a more accurate structural behavior so as to improve the safety of structures under extreme loading conditions. The soil-pile system behavior is predominantly nonlinear and this makes the problem complicated. In a laterally loaded pile the load is resisted by the soil-pile interaction effect, which in turn depends on soil properties, pile material, pile diameter, loading type and bed slope of ground. The difficulty in the accountability of the influencing factors necessitates a careful study on soil-structure interaction problem. The analysis became easier with the debut of powerful computers and simulation tools such as finite element analysis software. A detailed literature review on soil-structure interaction analysis of laterally loaded piles is presented in this paper.

“…e shape of p-y curves is largely affected by properties of the pile and the soil around the pile. Conventional p-y models are typically applicable to piles installed in horizontal ground [9][10][11][12]. Complex studies also have been carried out based on experimental and numerical investigations of piles installed in sloping ground.…”

“…Reese et al [22] presented a passive wedge model for soil around the pile subjected to lateral loads. Kim et al [12] developed a new hyperbolic p-y curve with an improved wedge model for representing a pile-soil interaction for laterally loaded piles in the ground. Similarly, Lin et al [23,24] proposed a simplified method for the analysis of laterally loaded piles in sand and clay under a scour condition based on a failure wedge model.…”

When a pile is placed near the slope, the lateral loading capacity of the pile decreases significantly due to the weakening effect of soil resistance near the slope. As such, a modified soil passive wedge model for near-slope laterally loaded piles is presented to consider the weakening effect in this paper. According to development depth of different wedges, the shapes of soil passive wedge can be classified into three sorts, so as to fully analyze the influence of the slope shape and the distance from the pile center to the slope crest. On this basis, a concept of equivalent depth is proposed considering the differences of laterally loaded piles near the slope and in the horizontal ground. Besides, the unit ultimate soil resistance, which can be obtained along the different depths of pile, is introduced into the p-y curve of the soil, for achieving solution methods of internal force and displacement of laterally loaded piles under the slope weakening effect. The results of laboratory model and field tests on laterally loaded piles are compared with the proposed method, demonstrating its validity and accuracy. Furthermore, the influence of the near-slope distance on the loading capacity of the pile is fully analyzed in detail, indicating the critical near-slope distance is increasing with the increase of the undrained strength, while independent of the slope angle.

“…The p-y approach is the most commonly used method since it can account for factors such as nonlinearity and soil layering (Matlock 1970). The p-y curve approach has been adopted by several researchers to analyze laterally loaded piles or group thereof (Reese et al 1974, Georgiadis et al 1992, Sawant et al 1996, Broms and Choa 1998, Mocwa and Duncan 2001, Dewaikar and Patil 2006, Chiou and Chen 2007, Kim et al 2009, Dewaikar et al 2009, Kodikara et al 2010, Kim et al 2011, Dewaikar et al 2011.…”

The paper presents the analysis of two groups of piles subjected to lateral loads incorporating the non-linear behaviour of soil. The finite element method is adopted for carrying out the parametric study of the pile groups. The pile is idealized as a one dimensional beam element, the pile cap as two dimensional plate elements and the soil as non-linear elastic springs using the p-y curves developed by Georgiadis et al. (1992). Two groups of piles, embedded in a cohesive soil, involving two and three piles in series and parallel arrangement thereof are considered. The response of the pile groups is found to be significantly affected by the parameters such as the spacing between the piles, the number of piles in a group and the orientation of the lateral load. The non-linear response of the system is, further, compared with the one by Chore et al. (2012) obtained by the analysis of a system to the present one, except that the soil is assumed to be linear elastic. From the comparison, it is observed that the non-linearity of soil is found to increase the top displacement of the pile group in the range of 66.4%-145.6%, while decreasing the fixed moments in the range of 2% to 20% and the positive moments in the range of 54% to 57%.
