基于FWD的层间结合状态分析方法

Analysis approaches based on FWD interlayer combination state

基于有限元理论,模拟FWD动载作用下路面的工作状态,对计算结果进行了分析,运用非线性多元回归等数值工具,对建立基于FWD的基层层间结合状态分析方法进行了探讨,从而建立一套基于FWD的基层层间结构状态分析方法。

Based on the finite element theory,simulating FWD pavement working state under dynamic loading,it analyzes the calculation results. Using the numerical tools of nonlinear multiple regression,it makes an exploration on establishing the analysis method based on FWD grass-roots interlayer structure combination state,then establishes an analysis method based on FWD grass-roots interlayer structure combination state.
