摘要 本研究主要討論的內容是探討在非均佈荷重作用下材料非線性之影響，說明如下： 本研究採用三維有限元素鋪面結構為分析模式，在探討在非均佈荷重作用下材料非線性之影響，本研究續用前人已將輪胎模型模擬成輪胎與鋪面表面的接觸應力條件下，再針對材料方面模擬為非線性模式，分析不同打氣胎壓與單軸雙輪載重作用下對鋪面的反應。分析結果顯示，鋪面的表面開裂將可能發生於雙輪中央處；而鋪面的表面車轍將可能發生在輪胎胎面下方處，並且破壞與重車的高胎壓、高軸重有關。所以更可以模擬出真實鋪面反應。 在路面績效評估方面，結合論文之第五、六節分析原理，應用於AI設計方法之車轍及疲勞龜裂模式理論，針對先前均佈與非均佈荷重情況下進行鋪面之績效分析。 ABSTRACT This study main disscuss about the influence of tire-pavement non-uniform contact stress with non- linear material. this study developed a 3-dimensional finite element model in disscussing the effects of tire-pavement non-uniform contact stress with non- linear material.This study ever developed a tire model to model tire-pavement non-uniform contact stress and in material aspect simulate a non-linear mode.The pavement respones results in different tire pressure and single axle two wheel show that the surface crack occurred center of two tires; and the surface rutting occurred under tire side. The distress relate with high tire pressure and axle load. So non-linear material can model the response of surface on pavement. In the performance-based pavement evaluation part, the study combine the fifth and sixth chapters and sections in analyze theorem.The application for the rutting and tired cracks mode theory of AI design method counter with non-uniform and uniform load to procced pavement effects.
