隨著社會主義市場經濟的深入發展，人們商品經濟觀念的增強，一些法制觀念淡薄的人，在經濟利益的驅動下，非法建築物佔用路產或在規定控制區內形成集市貿易、開山炸石、采礦作業、傾倒垃圾和建築廢料屢禁不止；非法利用、侵佔、污染、毀壞、破壞公路路產和盜竊公路交通設施、機具、設備、原材料、盜伐行道樹以及在公路上亂設站卡、亂收費、亂罰款，公路呈街道化蔓延；超限運輸等威脅著公路的完好、安全、暢通和公路事業的發展，公路的經濟效益、社會效益和路網服務水平的提高，越來越依靠于路政治理工作的加強。On the basis of the study of traffic features of heavy - load vehicles, the vehicle weight data and the axle - load spectrum of different vehicles were collected for some typical heavy - duty roads in china, and according to the features of heavy - loading pavement, deficiency of the former load - figure are analyzed and new figures which are suitable for heavy - load pavements are put forward. meanwhile, based on the research of the cement concrete fatigue equation and the damage mechanism of asphalt pavement under heavy - load vehicles, axle load conversion equations fitting for heavy - load cement concrete pavement and asphalt pavement are established respectively by further analysis. in addition, design indices, traffic and material parameters and structural combination for heavy - load pavements are discussed in this paper as well
本課題針對重載道路路面設計中所存在的問題，從重載交通特性出發，收集分析了國內幾條重載道路的交通及軸載組成情況，根據重載交通的特點，分析原有荷載圖式的不足，提出了適合於重載瀝青、重載水泥混凝土路面的荷載圖式；同時，在重載水泥混凝土路面疲勞方程及重載瀝青路面破壞機理研究的基礎上，通過對重載路面軸載換算公式的進一步研究，分別提出了適合於重載水泥及重載瀝青路面的軸載換算公式；此外，本文還對重載水泥、重載瀝青路面的設計指標、交通參數、材料參數及結構組合等方面進行探討，系統地提出了重載路面的設計方法，並使之有效地運用到工程實踐中。In the paper based on the study of mechanical property, durability, microstructure, engineering applying and theory of designation of hplc, the relation among the composition, structure and performance of iiplc, which is an essential theoretical base of hplc, is discovered. the main research work and compliments of this paper are : the concept on hplc is newly described from the aspect of development strategy, economic, demanding of technology of material. based on the analysis of the destroy theory and the research of property of the composition and structure of hplc, the ideology of designation of hplc, and the theory of interface strengthening and strength suiting are built ; the new method of designation of hplc which is based on the condition that the mixture has a high stability is invented ; a math modal is built to direct the designation of hplc
本文進行的主要工作和取得的重要成果有：從材料發展戰略、經濟性和技術要求角度，把高性能輕集料混凝土的設計水平分為三個層次進行評價，在此基礎之上提出了高性能輕集料混凝土的設計理念，用以指導設計、制備該類材料；在設計理念的指導下，結合對輕集料混凝土破壞機理的分析，提出了界面增強理論、強度匹配理論兩個主要的高性能輕集料混凝土設計理論；創立了基於拌和物穩定性控制的高性能輕集料混凝土設計新方法；建立了指導高性能輕集料混凝土設計的數學模型。For the structural engineering, the constitutive relations of concrete members under the strength will be nonlinear or elasticoplasticness, in this paper, ottosen constitutive model is adopted, and mohr - coulomb strength principle is selected as destructive principle, the concrete cantilever beam is analyzed by using nonlinear efgm, the calculation result by nonlinear efgm is compared with the analysis software of adina, the comparing proves that efgm used to dissolve the concrete nonlinear problem is feasible
目前，無網格伽遼金法主要研究都集中在線彈性材料上，在結構工程中，混凝土構件受力后的本構關系為非線性或彈塑性，本文首次在無網格伽遼金法中引入混凝土的ottosen本構模型和莫爾庫侖強度破壞準則，對混凝土懸臂梁等構件進行了非線性無網格分析，並與國際著名結構分析軟體adina的計算結果進行了對比，表明採用無網格伽遼金法解決混凝土非線性問題是可行的。分享友人
