Numerical Analysis of Single Piles Adjacent to Claytones Slope Under Lateral Load

The behavior of pile adjacent to slope differs from that of pile on level ground when subjected to lateral loads. As the distance increases, its behavior progressively resembles that of a pile on level ground. This study aims to analyze using the Midas GTS NX finite element software, which was performed by two modeling approaches, Hardening Soil model and Mohr-Coulomb model. The soil types analyzed consisted of silty clay layer on 0 to 3 m of depth and clay stone layer extending up to 40 m depth, meanwhile the pile were modeled as beam elements. Furthermore, this study also investigated the critical edge distance at which the pile behavior began to resemble closest to that of on level ground by testing the variations in slope ratio and pile distance from the slope crest then analyzing the response of both the pile and the surrounding soil comprehensively. Additionally, the study examined the distribution of deflection and bending moment in foundation pile subjected to lateral loads. The results indicate that as the slope steepens, the behavior of the foundation deviates further from the one on level ground and the influence of the slope becomes negligible when the foundation is located at a distance greater than 6D.
