| 中文摘要 | 本研究旨在探討機場鋪面設計中關鍵參數的敏感度,鋪面設計的發展經歷了經驗法、半經驗法到理論分析 法的轉變。早期設計依賴經驗法,根據觀察與操作經驗規劃鋪面結構。1940 年代土壤力學理論與試驗技術的進 步推動了半經驗法,透過推導出之經驗公式及圖表進行設計,並在 1960 年隨著美國國家公路與運輸官員協會 (American Association of State Highway and Transportation Officials,AASHTO)大型試驗道路的回饋,被廣泛 應用。而隨著數值分析及電腦模擬技術的快速發展,現代鋪面設計已逐漸過渡到理論分析法,係藉由軟體模擬鋪 面結構的應力分佈,為鋪面設計提供更為科學的依據。 本研究透過 FAA Rigid and Flexible Iterative Elastic Layered Design(FAARFIELD)軟體,針對剛性與柔性 鋪面的主要參數進行敏感度分析,包括離場架次、抗彎強度、路基強度、底層強度、底層厚度及設計年限,以瞭 解各參數對面層設計厚度的影響。此外,為了量化各參數的影響程度以及衡量不同參數之間的相對敏感度,採用 百分比及正規化兩種方式進行分析。研究結果顯示,在剛性鋪面中,路基強度及抗彎強度為最敏感之參數。而柔 性鋪面,則是路基強度、底層強度及厚度最為敏感。相較而言,離場架次與設計年限,對剛性與柔性面層設計厚 度的影響程度有限。 |
| 英文摘要 | This study focused on the sensitivity of parameters in airport pavement design. Pavement design has evolved from empirical methods to semi-empirical method and finally to theoretical analysis. Early pavement designs relied on empirical methods, using observations and experiences to decide pavement structures and thickness. In 1940s, advancements in soil mechanics and experiment technique led to semiempirical methods, which combined soil properties, pavement materials, and load data. This method has become widely used after the contributions from the AASHTO Road Test in 1960s. With modern advancements in computer simulations and numerical analysis, pavement design has started to shift to theoretical methods, using computer software to simulate stress distributions in pavement structure resulting in a more accurate and scientific results. This study applied FAARFIELD software by conducting sensitivity analysis of parameters which influencing pavement surface thickness for rigid and flexible pavements, which included departures traffic, concrete flexural strength, subgrade strength, base strength, base thickness and design life. To understand the influences to pavement surface thickness of these parameters, this study applied percentage analysis and normalization analysis to provide a thorough evaluation. The results showed that subgrade strength and flexural strength are the most sensitive parameters for rigid pavements. As for flexible pavements, subgrade strength, base strength, and base thickness have the greatest impact on pavement surface thickness. In contrast, departures traffic and design life have less influences on the thickness of both types of pavements. |
