摘要
本文在对评定思想理论论述的基础上,指出了现行评定方法的不足;继而提出了改进的连续迭代法,较好地解决了评定结果的唯一性问题。并应用四条试验路上的FWD(落锤式弯沉仪)实测弯沉数据,对评定模型进行了实际检验。
By analysing the backcalculation concept, some major problems in the existing evaluation approach are described. An improved self-iterative model which ensures a unique result is proposed, and FWD measurements made on four test pavements are used to identify the model.
