The paper is based on innumerable practical heavy - load road data , deliberate heavy - load standard in detail through theoretical arithmetic , and bring heavy - load standard about cement concrete pavement and asphalt concrete pavement separately ; in the meantime , through a large quantity of cement concrete pavement stress calculation , the paper puts forward relation expression between load on concrete board and stress level under board ; meanwhile , the paper puts forward traffic classification about cement concrete pavement and asphalt concrete pavement ; through bearing board testing on each structure sheaf the paper finds the material modulus gets modified ; through comparing position equivalent rebound modulus to theoretical equivalent rebound modulus , the paper points out limitation of nomograph in course of cement concrete pavement design , whereby , puts forward modifier formulas about theoretical equivalent modulus 本文以大量的重載道路資料為主,從實際出發,結合理論計算,對重載標準進行了詳細的討論,分別給出了水泥混凝土路面與瀝青混凝土路面的重載標準了;同時,通過大量的水泥混凝土板底應力計算,推導出了混凝土面板荷載與板底應力水平的關系式;給出了水泥混凝土路面與瀝青混凝土路面的交通分級;通過對試驗路各結構層進行承載板測試,發現現有材料模量較以前有了明顯的提高;對比現場實測的當量回彈模量與理論當量回彈模量,指出現有水泥路面設計中的諾謨圖不能完全符合現有道路材料,從而提出了對理論模量的修正公式。

Being deficient in sonic fatigue testing and owing to the limitations of nomograph method application to the sonic fatigue life prediction , an analysis software program was designed and worked out in present thesis , based on the research achievement in prediction of sonic fatigue life , which strong function , easy use and great extensive capabilities 本文針對現階段聲疲勞試驗的不足,以及工程中常用的諾謨圖方法的局限,整理了目前比較成熟的典型蒙皮壁板聲疲勞壽命研究成果,提出設計并編制了一套功能強、易于使用,可擴展性好的聲疲勞壽命預測及分析平臺。

In second part , a complete design and implement platform was constructed for sonic fatigue life analysis with the oriented - object programming design technique , as a replacement of nomograph method 在本文的后半部分,為了代替目前常用的列線圖求解聲疲勞響應方法,著重運用面向對象程序設計技術,完成聲疲勞壽命預測及分析平臺的設計和實現。

The result was shown that the program runs quickly and in reliability , it can replace the nomograph method and use easily for predicating sonic fatigue life of aircraft skin - panel structure 通過已有的算例進行驗證,結果表明計算迅速可靠,可以代替以列線圖為主要手段的求解方法,廣泛的應用于工程領域。
