【摘要】 通过试验,对加纤维聚合物的复合材料(FRP材料)与砂的界面性能作了初步的定性和定量的分析研究。结果表明:FRP材料与粒状材料界面的剪切性能,与法向应力的大小、相对粗糙度(表面粗糙度/颗粒的平均粒径)、砂体的初始密度、颗粒的棱角度有关;而剪切速率、土样的制备方法、样本的厚度对界面摩擦系数几乎没有影响。更多还原

【Abstract】 This paper describes the results of an experimental study that was conducted to investigate the behavior of sandFRP interfaces.Tests showed that the interface shear behavior between FRP composites and granular materials depended on the relative roughness (surface roughness/particle mean size),the normal stress level,the initial density of the soil mass,and the angularity of the particles.The soil specimen preparation method,the rate of shearing,and the thickness of the soil specimen had little influence on the measured interface friction coefficients.更多还原
