| 摘 要： | 根据实测路基回弹模量和弯沉值，通过回归分析和计算，提出适于实测路基的回弹模量与弯沉之间的换算公式，与规范中推荐的计算公式进行比较，结果表明，受不同地域、土质类型和含水量等因素的影响，通过实测建立路基回弹模量与弯沉值的相关关系，并根据设计路基回弹模量计算路基交工验收弯沉标准值，更有利于路基施工的质量控制。

| Abstract: | By testing the resilient modulus and deflection of subgrade, a conversion formula between resilient modulus and deflection has been obtained for the subgrade on regression analysis and calculation. The comparison result of different formula shows it is favorable to control subgrade construction quality using the deflection standard for acceptance check from the regression formula and designing resilient modulus of subgrade limited by the different influence of region, soil and moisture content. |
