摘要
根据系统识别法的基本原理,采用以灵敏度分析为基础的迭代法调整参数,对柔性路面结构进行位移动态反分析,编制柔性路面结构模量反算程序。研究结果表明,本文的反算方法稳定收敛,初始值对反算结果影响很小,反算结果精度较高,可在实际工程中应用。
According to the basic theory of system identification, parameters were adjusted by using iterative method based on sensitivity analysis. Modulus baekealeulateion program of the flexible pavement system was developped. The results show that the baekcalculation is high - precision, stably convergent and nearly independent of the original value.
