| 摘 要： | 采用改进直剪仪模拟桩与土之间的滑动摩擦,研究了沥青涂层对桩侧摩阻力的影响。试验结果表明,桩侧摩阻力与土的类型、法向应力有关,随着法向应力的增长,滑动摩阻力也相应增长,且增长近似呈线性关系;在一定的法向应力下,沥青涂层对减小滑动摩阻力有一定的作用,随着法向应力的增长,沥青涂层亦会导致滑动摩阻力增加。

| Abstract: | The sliding friction between the shoal soil and structural material by improved direct shear apparatus is simulated to study the effect of asphalt coating on the friction properties.The test results show that,the sliding friction is related to the soil type and normal stress.With the increase of normal stress,the sliding friction is growing and the growth shows nearly linear relationship.In certain normal stress,the asphalt coating plays a certain role in reducing the sliding friction,and with the increase of normal stress,the asphalt coating could increase the sliding friction. |
