【摘要】：道路建設項目，是一項涉及領域非常廣泛，影響因素眾多且技術性與政策性很強的工作，加之其工程難度大、工期長、投資大且影響深遠，所以在確定道路建設方案時，應該慎之又慎。道路選線工作是道路建設的首要工作，選線的合理與否直接決定了道路工程施工的具體方案，科學合理的選線方案，不但可以使構筑物穩(wěn)定耐久、易于養(yǎng)護，而且還可以提高行車的安全性及經(jīng)濟舒適性，真正地做到工程費用與使用質量的統(tǒng)一。所以進行道路選線設計時，應全面考慮各種因素的影響，應力求從工程本身、經(jīng)濟及社會等各個方面進行綜合考慮，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行分析，對目前我國道路選線現(xiàn)狀進行總結，提出其不足之處，在此基礎上，引入多目標綜合評價理論，對系統(tǒng)中各類指標的處理方法、賦權方法及綜合評價模型進行了詳細的分析，并以此為基礎構建了道路選線綜合評價指標體系。體系中以道路選線綜合最優(yōu)為總目標，以選線技術指標、經(jīng)濟指標與環(huán)境指標為子目標，并對各子目標選取相應的約束因素進行評價。對于子目標與總目標之間權重系數(shù)，本文采用改進的層次分析法進行計算；對于各約束因素與各指標之間的權重系數(shù)，本文考慮到主、客觀賦權法的優(yōu)缺點，采用改進的層次分析法與標準離差法相結合的綜合集成賦權法來確定其權重值，最后建立了線性加權綜合評價模型對各個備選方案進行綜合評價，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例，進行選線方案的多目標綜合評價。該實例證明了多目標綜合評價系統(tǒng)在道路選線優(yōu)化中的科學性與合理性，，也證明了本研究的重要意義。論文最后對研究內(nèi)容進行總結，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.
