1. Introduction. Over the past two decades, many high-speed railways have been constructed in China. In order to ensure that those high-speed railways can normally operate in design life, pile-supported embankments (GRPS) are widely adopted to reduce large differential settlement and postsettlement, for example, cement-fly ash-gravel (CFG) pile-supported …
