摘要

介绍了全风化及强风化软岩岩块作为高速铁路路堤的室内模型试验研究，得出了模型路堤基床系数K30、变形模量Ev1和变形系数Ev2等物理力学材料参数。采用Drucker-Prager材料有限元理论，分析了路堤在竖向准静循环荷载作用下的应力和变形特性，并与试验结果进行了比较，计算值和实测值较吻合，其对软岩岩土填筑路堤设计、施工与质量控制起到一定的借鉴作用。

Abstract

The indoor model experimental study on the physico-mechanical properties of pavement with weathered gravelly sands and argillite slate rock as the express railway embankment under quasi-static cyclic loads is introduced. Based on observations of some experiments

using biggest dry density and the optimum moisture content in its filling

the physico-mechanical properties including the moisture content of water

dry density

porosity ratio

angle of internal friction

cohesion value

displacements

stresses

permanent deformations

pressure distribution

bedding coefficient K30

deformation modulus Ev1 and deformation coefficient Ev2 of the embankment etc.

are obtained. With constitutive model for Drucker-Prager material

the stress and deformation characteristics of the pavement under quasi-static cyclic loads are analyzed by using finite element method. The numerical solutions are close with experimental ones. It is expected to put into use for design of pavement

control of compaction quality and construction in subgrade filling engineering.
