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。When the cement concrete pavement is opened to the traffic up to 3 ~ 5 years, especially when the wear resistance of the coarse aggregate is not good and the strength of the concrete pavement is not adequate, the wear in the original road surface will be more distinct in these cases. the phenomena of stripping, pit slot, surface pit, incompact and polish, filler damage and etc. usually happen in the cement concrete pavement. it will influence the traffic quality once the diseases appear in the cement concrete pavement
本論文結合東北高速黑龍江分公司項目《水泥混凝土路面白色薄層罩面技術的研究》展開工作,通過大量的試驗研究,從以往國內的修復材料,國外的同類材料中,參考道路修復材料的技術標準,路面養護維修手冊和混凝土路面修補技術要求,吸取已有材料的長處和特點,研製開發了kg水性修補材料和kg油性修補材料,通過反復測試並做正交試驗,研製出最優配方。Resulting from researches and experience accumulated in mbss practice for years, the author suggested a precision estimation model of depth and position for the acceptance of mbss systems, and presented further a stochastic model of double observation for data quality estimation. these models could be introduced to the designed national mbss acceptance standards
本文根據國際海道測量標準提出了多波束測深系統的水深和位置精度的評估模型,並提出了一種雙觀測法統計模型對測量數據的質量進行評估,其研究成果可以為建立我國多波束測深規范提供參考。On the basis of forecast model of traffic volume discussing, the mathematic model for the basic parts of road overpass was built up through the research on main mathematical model which suit for overpass in four - stage forecast method. according to the properties and the requirements of the user, by working on the service level, the standard of service level has been defined. the adaptability index of traffic for road overpass was put forward and an adaptability index of traffic system was established
