| 摘 要： | 高填方路基的稳定是多年来路基工程研究和关注的重点，高填方路基的稳定性与其计算参数取值密切相关。本项目采用大型三轴试验对贵州水都路的碎石土路基填料进行了试验研究，结果表明碎石土的抗剪强度与其应力水平密切相关。对于高填方路基的稳定计算参数取值应考虑路基的高度。

| Abstract: | The stability of high filled subgrade is always the research emphasis and focus of subgrade engineering for many years,which is closely related to the value of calculation parameters.In this paper,gravel soil subgrade filling of Guizhou Shuidu Road was studied through large-sale triaxial test.The results showed that the shear strength of gravel soil is closely related to its stress level.Therefore,the height of subgrade shall be considered when calculating stability parameters of high filled subgrade. |
