摘要
Abstract
New constructed passenger dedicated line demand that the post-construction settlement of the subgrade should be not more than 15 mm, and the current codes usually underestimate the ultima settlement for the sake of not taking lateral displacement effects into account. The lateral displacements of the toe with different fill heights and poisson' s ratios, and the relationships between maximum lateral displacements and settlements of central point of the passenger dedicated line, were investigated through conducting numerical simulations. The definition of correction coefficients of settlement was introduced and the relationships between the correction coefficients of settlement and fill heights/poisson' s ratios were analyzed.关键词
