中文摘要：
介绍了泥质板岩全风化及强风化料作为高速公路、高速铁路路堤的室内模型试验研究,采用不同的颗粒级配、不同的含水量,通过施加不同的竖向荷载作用于模型路堤,获取了路堤面板的沉降以及堤内应力、应变、土压力值和变形性状以及模型路堤的极限承载力等,试验结果表明模型路堤内的应力、应变和沉降位移随堤面竖向荷载、含水量和颗粒粒径不同而变化。它将对软岩风化料填筑高速铁路路堤设计、施工与质量控制起到一定的借鉴作用。
英文摘要：
This paper introduced the physical and mechanics properties and stability of indoor model test of weathered argillite slate rock as the highway and the express railway embankment under the loads. Based on observations of different vertical loads, various water quantity and suitable grains scale, physical and mechanics properties, such as subsiding displacements, stresses, permanent deformations, pressure distribution of the embankment , ultimate bearing capacity of the pavement and so on, were obtained. The result of the model test shows that the subsiding displacement varies with vertical loads, water content and the weathered soft rock grains scale. It is expected to put into use for design of pavement, control of compaction quality and construction in subgrade filling engineering .
