【摘要】：為適應(yīng)我國(guó)高速公路建設(shè)日益向?yàn)r青路面維修養(yǎng)護(hù)方向轉(zhuǎn)移的發(fā)展趨勢(shì)，瀝青路面大修養(yǎng)護(hù)建設(shè)已引起國(guó)內(nèi)外的廣泛關(guān)注。但目前對(duì)大修方案決策未建立起規(guī)范和統(tǒng)一的決策工作流程，推薦方案多根據(jù)決策者經(jīng)驗(yàn)定性的確定，缺少方案評(píng)估指標(biāo)和定量的方案優(yōu)選計(jì)算方法，在一定程度上制約著大修養(yǎng)護(hù)事業(yè)的發(fā)展。因此，針對(duì)當(dāng)前大修工程決策隨意性大的現(xiàn)狀，加強(qiáng)和規(guī)范瀝青路面大修設(shè)計(jì)與方案決策研究具有重要的現(xiàn)實(shí)意義。 在現(xiàn)場(chǎng)調(diào)查和文獻(xiàn)檢索的基礎(chǔ)上，總結(jié)了面臨大修的瀝青路面主要病害種類和特點(diǎn)，提出路面使用性能評(píng)價(jià)指標(biāo)和標(biāo)準(zhǔn)。根據(jù)路況評(píng)價(jià)結(jié)果，總結(jié)了不同指標(biāo)標(biāo)準(zhǔn)下的維修對(duì)策，為大修候選方案的確定提供依據(jù)。 總結(jié)分析國(guó)內(nèi)外常用大修方案的適用性和設(shè)計(jì)方法，詳細(xì)介紹了瀝青路面加鋪方案、翻修方案和再生方案三種典型大修方案的特點(diǎn)、適用性和設(shè)計(jì)方法，為路面大修候選方案設(shè)計(jì)和方案評(píng)估工作奠定基礎(chǔ)。結(jié)合工程實(shí)例，進(jìn)行大修方案決策和選擇方法的分析，指出目前在確定路面大修工程推薦方案時(shí)存在的選擇問題�；诖�，提出大修方案選擇方法設(shè)計(jì)過程中擬解決關(guān)鍵點(diǎn)。 參考大量研究資料，論證了采用多屬性決策法作為大修方案選擇方法的可行性，從確定可行候選方案、提出大修方案評(píng)估指標(biāo)、確定評(píng)估指標(biāo)的權(quán)重三個(gè)方面進(jìn)行了大修方案選擇方法的研究，建立了多屬性決策法確定大修推薦方案的工作流程圖。 基于大修工程實(shí)例方案分析，從經(jīng)濟(jì)、技術(shù)、效益和可行性四方面提出了瀝青路面大修工程方案評(píng)估指標(biāo)，采用層次分析法確定了瀝青路面大修方案評(píng)估指標(biāo)的權(quán)重。最終提出瀝青路面大修方案的優(yōu)選方法，并進(jìn)行了示例應(yīng)用。 通過量化的瀝青路面大修方案優(yōu)選方法，，采用科學(xué)的數(shù)值計(jì)算，簡(jiǎn)化瀝青路面大修方案選擇過程，在大修方案選擇過程提供了有效的數(shù)據(jù)依據(jù)，從真正意義上達(dá)到大修方案優(yōu)選的技術(shù)可行性、可靠性和科學(xué)性，對(duì)完善道路大修方案決策研究和提高道路大修技術(shù)水平具有重大意義。
[Abstract]:In order to adapt to the development trend of the highway construction in our country are transferring to the direction of maintenance of asphalt pavement, asphalt pavement maintenance construction has attracted wide attention both at home and abroad. But the overhaul decision did not set up a standardized and unified decision-making process, the recommended scheme is determined according to the experience of decision makers more qualitative, lack of calculation method of optimal scheme project evaluation index and quantitative, to a certain extent restricts the development of overhaul maintenance enterprises. Therefore, in view of the current situation of the arbitrariness of the overhaul project decision-making, strengthen and has important practical significance to research on asphalt pavement design specification and project decision overhaul.
Based on field investigation and literature research, summarizes the main diseases of asphalt pavement overhaul face types and characteristics, put forward the pavement performance evaluation index and standard. Based on the evaluation results, summarizes the different indexes under the standard maintenance strategy, and provide the basis for the overhaul of candidate solutions.
Summarize the applicability analysis and design methods commonly used at home and abroad overhaul scheme, detailed scheme and paving asphalt pavement, characteristics of three typical overhaul plan revision scheme and regeneration scheme, applicability and design method for pavement design and evaluation of candidate scheme foundation. Combined with the engineering example, analysis of overhaul plan decision and the selection methods, and points out that the selection of problems in determining pavement recommending. Based on this, puts forward the repairing scheme selection method in the design process to solve the key point.
Reference to a large number of data, demonstrates the feasibility of using multiple attribute decision making method for overhaul scheme selection method, from determining the feasible alternatives proposed overhaul scheme evaluation index, the choice of methods overhaul plan three aspects to determine the weight of evaluation index is established to determine the flow chart of overhaul the recommended scheme of multi attribute decision making method.
Based on the analysis, examples of program overhaul project from the economic, technology, four aspects of efficiency and feasibility of proposed evaluation index of asphalt pavement overhaul engineering scheme, using AHP to determine the weights of assessment indexes of asphalt pavement overhaul scheme. Finally put forward the optimization method of repairing scheme of asphalt pavement, and the application example.
Through the optimization method of asphalt pavement overhaul scheme to quantify, using scientific numerical calculation, simplified asphalt pavement overhaul scheme selection process, the selection process in the overhaul scheme provides effective data for the technical feasibility, from the real sense to overhaul scheme optimization, reliability and scientific, to improve and improve the decision-making research is of great significance the overhaul project of road technical level of road overhaul.
