【摘要】 针对当前重载交通状况 ,现行公路水泥混凝土路面设计规范存在明显不足。在总结国内外研究成果的基础上 ,从混凝土疲劳特性入手 ,提出了曲线疲劳方程 ,并根据国内已有的小梁疲劳试验结果重新回归出了曲线疲劳方程。根据曲线疲劳方程推导出了重载车辆轴载换算公式从而能更加合理地反映实际情况 ,适应当前重载交通需要。更多还原

【Abstract】 Today’s heavy-load traffic leads to the failure of the specifications of cement-concrete-pavement design. Based on the newest research at home and abroad,started with the fatigue features of cement concrete,the paper puts forward the fatigue equation of curve,and return the curvilinear fatigue equation again on the basis of the fatigue test existing.Meanwhile,the heavy load axle conversion have been infered on the basis of the curvilinear fatigue equation.This can resonably reflect the material’s characteristic about cement concrete and better adapt today’s heavy load traffic condiction.更多还原
