【摘要】：我國的高速公路建設最近幾十年取得了飛速的發(fā)展,隨著高速公路通車里程的增加,高速公路特別是瀝青路面高速公路的路面使用性能評價越來越重要。高速公路瀝青路面的使用功能隨著時間推移逐年下降,甚至會出現車轍、裂縫、沉陷、龜裂等破損病害,嚴重影響路面的舒適性,甚至影響到行車安全。所以說對高速公路路面使用性能評價的研究就顯得十分必要和有意義。本文首先介紹了國內外對于路面使用性能評價系統(tǒng)的研究現狀,結合我國工程的實際情況對路面檢測的新技術做詳細的論述。其次,對我國高速公路路面評價的影響要素、評價指標和評價標準做了深入的剖析和探討。瀝青路面規(guī)范對路用性能的評價指標和標準做了規(guī)定,本文結合惠河高速的實際情況,對其路面路用性能的檢測和評價做了研究。最后,以TOPSIS法為依托進行了惠河高速公路選取路段的綜合評價,并與規(guī)范評定指標評定結果做了對比。然后運用Abaqus有限元軟件,分別評價在標準軸載和重荷載作用下廣東惠河高速的路面結構力學性能,以此驗證路面結構設計的準確性。本文將TOPSIS評價方法引入到對瀝青路面質量評價當中,且采用了主客觀相結合的賦權方法對指標進行賦權,使瀝青路面的評價更加客觀準確,從而為高速公路瀝青路面的評價提供借鑒和參考,其現實應用的意義深遠。
[Abstract]:The expressway construction in our country has made rapid development in recent decades. With the increase of expressway mileage, it is more and more important to evaluate the pavement performance of expressway, especially asphalt pavement expressway. With the passage of time, the use function of highway asphalt pavement will decline year by year, even will appear rutting, crack, subsidence, crack and other damaged diseases, seriously affect the comfort of the road, and even affect the driving safety. Therefore, it is very necessary and meaningful to study the evaluation of expressway pavement performance. This paper first introduces the research status of pavement performance evaluation system at home and abroad, and discusses in detail the new technology of pavement detection combined with the actual situation of China's engineering. Secondly, the influencing factors, evaluation indexes and evaluation criteria of expressway pavement evaluation in China are analyzed and discussed in depth. The evaluation index and standard of pavement performance are stipulated in the specification of asphalt pavement. Combined with the actual situation of Huihe high speed, the detection and evaluation of pavement performance are studied in this paper. Finally, the comprehensive evaluation of selected sections of Huihe Expressway based on TOPSIS method is carried out, and the results are compared with the standard evaluation index. Then the mechanical properties of the pavement structure of Huihe highway in Guangdong province under the action of standard axle load and heavy load are evaluated by using Abaqus finite element software to verify the accuracy of pavement structure design. In this paper, the TOPSIS evaluation method is introduced into the evaluation of asphalt pavement quality, and the subjective and objective weighting method is used to weight the index, which makes the evaluation of asphalt pavement more objective and accurate. Thus, it provides reference and reference for the evaluation of highway asphalt pavement, and its practical application is far-reaching.
