摘要
采用轴对称动力有限元结合系统识别反分析理论进行路面模量反算,考虑了落锤式弯沉仪(FWD)荷载作用下的路面反应动力效应。通过两个算例分析,体现出与拟静力反分析相比,动力反分析更符合实际,而拟静力法只有在基岩深度较深时是合理的。
This essay adopts limited units of axial symmetry and theory of system recognizing backcalculation,in which the dynamic effect of the road surface reaction to load of FWD is considered.Through the analysis of the two examples,dynamic backcalculation is more practical when compared with backcalculation of simulated static,whereas backcalculation of simulated static is practical only when the depth of bedrock is very deep.
