諾謨圖 的英文怎麼說
中文拼音 [nuòmótú]
諾謨圖
英文
abac-
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，提出設計並編制了一套功能強、易於使用，可擴展性好的聲疲勞壽命預測及分析平臺。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。
