摘要
近20 a来,高速公路建设中红层软岩大量用作路堤填料,但对其抗剪强度特性及试验方法缺乏深入研究。根据湖南省湘潭至衡阳西线高速公路k123+600-k124+700段路堤的10个现场大型水平推剪试验,得出了红层软岩土石混合填料体的变形特点和相关的抗剪强度参数,为路堤的稳定性分析提供了必要的依据,同时也为其他类似材料的力学性质研究提供了一个可能的途径。
Recently 20 years, as road foundation' s fillings, red beds rock has been widely used in highway constraction. But lack of deeply research in its' characters of shear strength and correspongding test methods, Based on 10 horizonal push-shear in-situ tests in k123 + 600 -k124 + 700 of Xiang(Tan) Heng(Yang) West Highway, this paper gained red beds soil-rock fillings' deformed feature and paramters of shear strength, this supply materials to road-foundation' s stability analysis. At the same time, the pross provided a reference path to analysis mechanical characters of other similar materials.
