Modeling of Pervious Pile-Supported Embankment Under the Consolidation Process
Pile supported and geosynthetics reinforced embankments are widely used in construction in recent years, especially for highway and high-speed railway as an effective method to improve the bearing capacity and to reduce the settlement of the foundation. As an improvement, pervious piles can be used as drainage elements in addition to vertical reinforcement as they can increase both the rate of consolidation and the bearing capacity of soft foundations. The purpose of this study is to investigate the behaviour of pervious pile-supported embankment during the consolidation process. A series of finite element models were established using the software PLAXIS to investigate the consolidation of soft soil. It was observed that the variation of stress concentration from soil to the pile is consistent with the consolidation of the foundation soil. In general, the rate of consolidation affects the rate of stress concentration. Parametric study showed that the larger the modulus ratio of the pile and the soil, the larger the stress acting on the pile, and the absolute size of the pile has a greater influence on stress distribution between soil and pile than the relative volume of pile and soil has.
