Abstract

Pile-supported low embankments offer significant advantages, such as enhancing the bearing capacity of the subgrade, reducing subgrade settlement, and mitigating the drawbacks associated with high embankments, including excessive land occupation and environmental concerns. However, a conclusive definition of the critical height of pile-supported low embankments and a standardized classification method for distinguishing between high and low embankments remain lacking. In this study, a series of numerical models of pile-supported embankments under plane strain conditions were developed using ABAQUS. The variations in pile-soil stress ratio, plastic zone height, shear plane distribution characteristics, and relative differential settlement with respect to embankment height were systematically analyzed and summarized. Based on these variations, the pile-supported embankments were classified according to height. The results indicate that the relationship between the pile-soil stress ratio, shear surface distribution characteristics, and embankment height is influenced by pile spacing and the friction angle, which can be broadly categorized into two types. Notably, the friction angle does not affect the critical height of the embankment or its classification. Compared to existing classification theories, the proposed method in this study provides a more reasonable and comprehensive framework for understanding the behavior of pile-supported embankments.
