【摘要】：近年來,鐵路建設(shè)尤其是中西部的鐵路建設(shè)進入了新的快速發(fā)展階段,在帶動周邊經(jīng)濟發(fā)展的同時,不可避免的對周圍環(huán)境造成一定的影響。尤其是在西部地區(qū),線路周邊生態(tài)系統(tǒng)極其脆弱,環(huán)境破壞的可恢復(fù)性差。在可持續(xù)性發(fā)展的要求下,鐵路選線必須綜合考慮鐵路建設(shè)、運營、環(huán)境保護等因素的影響。引入綠色鐵路選線的相關(guān)概念,研究選線設(shè)計的多目標(biāo)比選方法就顯得尤為必要。論文在充分研究現(xiàn)有的選線方案多目標(biāo)決策系統(tǒng)的基礎(chǔ)上,結(jié)合西部鐵路建設(shè)的具體工程,從工程、環(huán)境、運營等方面出發(fā),進一步細化決策影響因素,完善基于綠色概念的鐵路選線方案比選系統(tǒng)。論文主要完成了以下幾方面工作:(1)從技術(shù)條件、經(jīng)濟、環(huán)境影響以及社會效益四個方面研究線路多目標(biāo)比選體系的主要影響因子,選擇具有代表性的影響因素,構(gòu)建多層次的指標(biāo)體系結(jié)構(gòu)模型。(2)采用層次分析法法求解出各準(zhǔn)則層以及子準(zhǔn)則層內(nèi)的所有指標(biāo)的權(quán)重值。深入分析常見的各種鐵路線路方案評價方法的特點,考慮到影響鐵路線路方案的因素的定性、定量特性,確定了模糊綜合評價法和灰色相關(guān)理論相結(jié)合的多目標(biāo)評價方法。(3)根據(jù)模糊綜合評價法及灰色相關(guān)理論方法的相關(guān)分析,從定性及定量的角度分別建立了基于綠色概念的線路方案評判模糊綜合評價模型,以及基于灰色相關(guān)理論的線路方案評判模型,并研究二者相結(jié)合的線路方案綜合評價方法。(4)以南疆鐵路的具體工程為研究背景,采用灰色相關(guān)理論對定量指標(biāo)(即技術(shù)條件指標(biāo)及經(jīng)濟指標(biāo))進行評價分析,采用模糊綜合評價法對定性指標(biāo)(即環(huán)境影響指標(biāo)及社會效益指標(biāo))進行綜合評價分析,建立基于模糊綜合評價及灰色相關(guān)理論方法的線路方案評判分析模型,根據(jù)指標(biāo)體系的層次結(jié)構(gòu)進行多級模糊綜合評價,得到各方案的優(yōu)劣次序。決策結(jié)果與實際線路方案比選結(jié)果一致,也驗證了所選取的評價方法的合理性及有效性。論文整體研究對于綠色選線概念的有效推廣,尤其是對西部干旱生態(tài)脆弱環(huán)境區(qū)域的選線設(shè)計具有十分重要的理論及實用價值。
[Abstract]:In recent years, railway construction, especially the railway construction in the central and western regions, has entered a new stage of rapid development. While driving the development of the surrounding economy, it inevitably has a certain impact on the surrounding environment.Especially in the western region, the ecosystem around the line is extremely fragile, and the recovery of environmental damage is poor.Under the requirement of sustainable development, railway line selection must take into account the influence of railway construction, operation, environmental protection and so on.It is necessary to introduce the concept of green railway route selection and to study the multi-objective selection method of route selection design.On the basis of fully studying the existing multi-objective decision-making system of route selection scheme and combining with the specific project of the western railway construction, the paper further refines the influencing factors of decision making from the aspects of engineering, environment, operation and so on.Improve the railway line selection system based on green concept.The main work of this paper is as follows: (1) to study the main influencing factors of multi-objective selection system in terms of technical conditions, economy, environmental impact and social benefits, and to select representative influencing factors.A multi-level index architecture model is constructed. (2) Analytic hierarchy process (AHP) is used to calculate the weights of all indexes in each criterion layer and sub-criterion layer.Deeply analyzing the characteristics of common evaluation methods for railway line schemes, taking into account the qualitative and quantitative characteristics of the factors affecting railway line schemes,According to the correlation analysis of fuzzy comprehensive evaluation method and grey correlation theory method, the multi-objective evaluation method combining fuzzy comprehensive evaluation method with grey correlation theory is determined.The fuzzy comprehensive evaluation model of line scheme evaluation based on green concept and the line scheme evaluation model based on grey correlation theory are established from the qualitative and quantitative aspects respectively.Based on the research background of the concrete project of the southern Xinjiang railway, the quantitative index (i.e. technical condition index and economic index) is evaluated and analyzed by grey correlation theory.The fuzzy comprehensive evaluation method is used to evaluate and analyze the qualitative indexes (that is, environmental impact index and social benefit index), and the evaluation and analysis model of route scheme based on fuzzy comprehensive evaluation and grey correlation theory is established.According to the hierarchical structure of the index system, the multilevel fuzzy comprehensive evaluation is carried out, and the advantages and disadvantages of each scheme are obtained.The result of the decision is consistent with that of the actual route scheme, and the rationality and effectiveness of the evaluation method are verified.The whole study of this paper is of great theoretical and practical value for the effective extension of the concept of green route selection, especially for the design of route selection in arid ecological fragile environment areas in western China.
