【摘要】：道路建設(shè)項(xiàng)目，是一項(xiàng)涉及領(lǐng)域非常廣泛，影響因素眾多且技術(shù)性與政策性很強(qiáng)的工作，加之其工程難度大、工期長、投資大且影響深遠(yuǎn)，所以在確定道路建設(shè)方案時(shí)，應(yīng)該慎之又慎。道路選線工作是道路建設(shè)的首要工作，選線的合理與否直接決定了道路工程施工的具體方案，科學(xué)合理的選線方案，不但可以使構(gòu)筑物穩(wěn)定耐久、易于養(yǎng)護(hù)，而且還可以提高行車的安全性及經(jīng)濟(jì)舒適性，真正地做到工程費(fèi)用與使用質(zhì)量的統(tǒng)一。所以進(jìn)行道路選線設(shè)計(jì)時(shí)，應(yīng)全面考慮各種因素的影響，應(yīng)力求從工程本身、經(jīng)濟(jì)及社會等各個(gè)方面進(jìn)行綜合考慮，從而得到最理想的方案。 本文通過對道路選線的基本理論進(jìn)行分析，對目前我國道路選線現(xiàn)狀進(jìn)行總結(jié)，提出其不足之處，在此基礎(chǔ)上，引入多目標(biāo)綜合評價(jià)理論，對系統(tǒng)中各類指標(biāo)的處理方法、賦權(quán)方法及綜合評價(jià)模型進(jìn)行了詳細(xì)的分析，并以此為基礎(chǔ)構(gòu)建了道路選線綜合評價(jià)指標(biāo)體系。體系中以道路選線綜合最優(yōu)為總目標(biāo)，以選線技術(shù)指標(biāo)、經(jīng)濟(jì)指標(biāo)與環(huán)境指標(biāo)為子目標(biāo)，并對各子目標(biāo)選取相應(yīng)的約束因素進(jìn)行評價(jià)。對于子目標(biāo)與總目標(biāo)之間權(quán)重系數(shù)，本文采用改進(jìn)的層次分析法進(jìn)行計(jì)算；對于各約束因素與各指標(biāo)之間的權(quán)重系數(shù)，本文考慮到主、客觀賦權(quán)法的優(yōu)缺點(diǎn)，采用改進(jìn)的層次分析法與標(biāo)準(zhǔn)離差法相結(jié)合的綜合集成賦權(quán)法來確定其權(quán)重值，最后建立了線性加權(quán)綜合評價(jià)模型對各個(gè)備選方案進(jìn)行綜合評價(jià)，得出最優(yōu)的選線方案。 本文選取滁州市某一道路選線工程實(shí)例，進(jìn)行選線方案的多目標(biāo)綜合評價(jià)。該實(shí)例證明了多目標(biāo)綜合評價(jià)系統(tǒng)在道路選線優(yōu)化中的科學(xué)性與合理性，，也證明了本研究的重要意義。論文最后對研究內(nèi)容進(jìn)行總結(jié)，并提出了該研究的不足之處及今后的努力方向。
[Abstract]:Road construction projects, involving a very wide field, many influencing factors and technology and work with very strong policy, coupled with the construction difficult, long construction period, large investment and a far-reaching influence, so in determining the road construction project, should be cautious. Road alignment is the first work of road construction, selection the line is reasonable or not directly determine the specific project of road engineering construction, scientific and reasonable scheme can not only make the structure stable and durable, easy to maintain, but also can improve the traffic safety and economic comfort, truly achieve the engineering cost and service quality. So the unified road alignment design that should fully consider various factors, should be sought from the project itself, the economic and social aspects of a comprehensive consideration, so as to get the optimal solution.
In this paper, through the analysis of the basic theory of line selection on the road, the current road line selection are summarized, put forward the deficiencies, on this basis, the introduction of multi objective comprehensive evaluation theory, method of dealing with all kinds of index system, weighting method and comprehensive evaluation model are analyzed in detail, and then the foundation of the road line selection system. The comprehensive evaluation index system to comprehensive optimal road line selection for the overall objective of the line selection of technical indicators, economic indicators and environmental indicators as the target, and select the corresponding constraint factors to evaluate each sub goal. The weight coefficient between the target and the overall goal, the the improved AHP for weight coefficient calculation; between the various factors and constraints of each index, considering the main advantages and disadvantages, objective weighting method, using AHP and improved standard deviation The comprehensive weighting method is used to determine the weight value. Finally, a linear weighted comprehensive evaluation model is established to evaluate the alternatives comprehensively, and the best line selection plan is obtained.
This paper selects a Chuzhou road line selection project, multi-objective comprehensive evaluation of line selection scheme. The examples prove that the multi-objective comprehensive evaluation system on road alignment optimization is scientific and reasonable, also proved the importance of this research. At the end of this paper summarizes the research contents, and put forward limitations of this study and future direction.
