鋪面系統在行進載重作用下之動態反應，常受鋪面材料、基礎土層性質及
載重型式等動態參數之影響，本研究將進行鋪面系統在移動載重作用下之
動態反應分析，探討多重載重、追逐載重、鋪面頻率內涵、鋪面及土層之
動態性質及環境溫度等對鋪面系統動態反應所造成之影響，然後利用實際
鋪面系統進行實例分析，並與理論分析結果做一比較，期能將研究結果提
供道路系統之鋪面設計及道路規範修正之重要參考。研究結果顯示，鋪面
及土層剪力模數、柏松比，鋪面厚度及鋪面之頻率，對於鋪面動態反應之
影響相當大；多重載重、追逐載重及載重行進效應，在進行鋪面設計時，
應納入考慮。

The dynamic responses of pavement systems subjected to moving
loads are affected by properties of the pavement，properties of
the soil,and types of the loading.The main purpose of this
research is to investigate the behavior of pavement systems
subjected to moving loads.Effect of multiple loadings,
velocities of loadings,frequencies of the pavement,dynamic
properties of the pavement and the soil, and the temperature of
the pavement are all studied.The dynamic behavior of a real
pavement system is also investigated and compared to these
obtained by analytical studies. Results of this study shows
that the dynamic responses of the pavement systems are strongly
affected by shear moduli,Poisson's ratios,thicknesses, and the
frequency contents of the pavement. It is also suggested that
velocities of loadings and the effects of moving loads be
considered in the pavement designs.
