柔性路面结构层模量反算方法研究

The Research of the Moduli Back-calculation Method for Flexible Pavement Layers Ni Fujian

本文以弯沉数据库和优化法相结合，编制了模量反算程序ＤＭＢＭ。此外，还编制了与之配套使用的具有更高精度的反算程序ＢＰＭＰ。计算表明，这种处理方法既可保证精序又可提高速度，与国外反算程序相比，这套程序显示出良好的计算性能和较好的实用性能。

In this paper,an optimization method combined with a deflection data-base ispresented.Furthermore,a program DMBM recomended,and a program BPMP which is incooperation with DMBM with better acccuracy is also completed.The results show that thismethod not only can guarantee the accuracy but also can speed up the calculation in compar-ing with back-calculation programs abroad.The set of programs manifest good calculatingcapacity and practicality.
