Abstract

With the first high speed trains (HST) emerging in the United States, it is critical to develop better understanding of the design and performance requirements for HST track embankments. One of the main challenges in this process is to determine proper track embankment design criteria, specifically stiffness criteria to meet the acceptable deformation limits considering the maximum design speed. This study investigates the long-term deformations of HST track embankments on soft clay subgrades. The required thickness and stiffness (deformation modulus) for track embankment layers to meet the maximum deformation criteria were evaluated for a typical at-grade embankment section. A nonlinear, th..
