Abstract: A framework of structural stiffness evaluation for flexible pavement, which is based on the deflection basin, is presented. By analysing the character of surface deflection basins, a conception of deflection sections is proposed, a self-iterative model is used to calculate the stiffness, and a computer program is developed.

摘要： 本文给出了实测弯沉盆基础土的柔性路面刚度组成分析的框架,在全面分析了弯沉盆特性之后,提出了弯沉段的概念,在此基础上引入连续迭代法分析路面的刚度组成,并编制了相应的计算机分析程序。
