【摘要】：復(fù)雜艱險(xiǎn)山區(qū)線路總體設(shè)計(jì)工作是一項(xiàng)復(fù)雜的系統(tǒng)工程。一方面線路方案選定是一件關(guān)系到全局的總體性工作,綜合性強(qiáng),牽涉面廣,涉及到多學(xué)科的綜合應(yīng)用,本身就是一項(xiàng)復(fù)雜的工作;另一方面復(fù)雜艱險(xiǎn)山區(qū)中地質(zhì)災(zāi)害頻發(fā),且災(zāi)害成因復(fù)雜多變,之間又相互作用,為線路建設(shè)增添了巨大的難度。因此,復(fù)雜艱險(xiǎn)山區(qū)線路設(shè)計(jì)很難用簡(jiǎn)單的方式進(jìn)行,應(yīng)該從系統(tǒng)角度出發(fā)進(jìn)行總體設(shè)計(jì),統(tǒng)籌處理好各專業(yè)間、整體與局部間的協(xié)調(diào)關(guān)系。通過吸取其他學(xué)科總體設(shè)計(jì)的成功經(jīng)驗(yàn),結(jié)合已有的研究成果,并以參研的“高海拔大高差艱險(xiǎn)山區(qū)鐵路綜合勘察與總體設(shè)計(jì)理論及工程應(yīng)用研究”課題為依托,本文規(guī)范化了復(fù)雜艱險(xiǎn)山區(qū)線路總體設(shè)計(jì)的作業(yè)程式,認(rèn)為應(yīng)該強(qiáng)調(diào)三階段的設(shè)計(jì)流程:子系統(tǒng)劃分、子系統(tǒng)優(yōu)化和大系統(tǒng)綜合評(píng)價(jià),并根據(jù)線路工程的特點(diǎn),針對(duì)各階段分別提出了相應(yīng)的定量化研究方法。首先,針對(duì)子系統(tǒng)的劃分,總結(jié)了線路工程按區(qū)間段或不同專業(yè)劃分子系統(tǒng)的傳統(tǒng)方法,隨后提出從災(zāi)害角度出發(fā),將復(fù)雜艱險(xiǎn)山區(qū)線路工程系統(tǒng)劃分為承災(zāi)體子系統(tǒng)和致災(zāi)體子系統(tǒng),并采用ISM定量化分析方法,對(duì)滑坡致災(zāi)子系統(tǒng)進(jìn)行了進(jìn)一步的分解作業(yè)。其次,在對(duì)承災(zāi)體子系統(tǒng)進(jìn)行優(yōu)化時(shí),采用了一種特別適合解決多種因素間相互作用問題的方法一相互作用矩陣法,考慮各子系統(tǒng)間相互作用的同時(shí)將其作用強(qiáng)度定量化。并以通過八渡滑坡工點(diǎn)的線路方案比選為例,詳細(xì)說明了該方法在優(yōu)化線路工程子系統(tǒng)時(shí)的具體操作。在對(duì)區(qū)間段子系統(tǒng)進(jìn)行優(yōu)化時(shí),提出了一種以保證線路通過能力均衡為約束、經(jīng)濟(jì)最省為目標(biāo)的線路區(qū)間段子系統(tǒng)優(yōu)化程式,并結(jié)合改善吉加公路Besi至Betrawati段通過能力不均衡的案例,說明了其具體操作過程。最后,在大系統(tǒng)綜合評(píng)價(jià)時(shí),構(gòu)建了一種基于變權(quán)和灰色關(guān)聯(lián)度決策的評(píng)價(jià)模型。該模型能夠在主客觀權(quán)重結(jié)合的基礎(chǔ)上,綜合考慮各定量和定性評(píng)價(jià)指標(biāo),完成科學(xué)全面的評(píng)價(jià),隨后以川藏鐵路然烏-玉普段四個(gè)通過方案評(píng)價(jià)比選為例進(jìn)行了實(shí)例分析。
[Abstract]:The overall design of complex and dangerous mountain area line is a complicated system engineering. On the one hand, the selection of the route scheme is an overall task related to the overall situation, with strong comprehensiveness, extensive involvement, and comprehensive application of various disciplines, which is itself a complex task; on the other hand, geological disasters frequently occur in the complex and dangerous mountain areas. The formation of disasters is complex and changeable, and the interaction between them adds great difficulty to the construction of lines. Therefore, it is difficult to carry out the design of complex and dangerous mountain lines in a simple way, so the overall design should be carried out from the system point of view, and the coordination relationship between the professions, the whole and the parts should be handled as a whole. By drawing on the successful experience of the overall design of other disciplines, combining with the existing research results, and relying on the subject of "Comprehensive investigation and overall design theory and engineering application of railway in mountainous areas with large and dangerous altitude and great difference at high altitude", This paper standardizes the operation program of the overall design of the complex and dangerous mountain areas, and considers that the design flow of three stages should be emphasized: subsystem division, subsystem optimization and comprehensive evaluation of large systems, and according to the characteristics of the line engineering, The corresponding quantitative research methods are put forward for each stage. First of all, aiming at the division of subsystems, this paper summarizes the traditional methods of dividing subsystems according to interval or different specialties in line engineering, and then puts forward a disaster perspective. The railway engineering system of complex and dangerous mountain area is divided into disaster bearing subsystem and disaster causing subsystem, and the landslide disaster subsystem is further decomposed by using ISM quantitative analysis method. Secondly, in the optimization of the disaster bearing subsystem, an interaction matrix method, which is especially suitable for solving the interaction problem between many factors, is adopted. The interaction intensity of each subsystem is quantified while considering the interaction between the subsystems. The concrete operation of this method in optimizing the line engineering subsystem is explained in detail by comparing the route scheme of the Badu landslide work site with an example. In the optimization of interval segment system, an optimization program of line interval segment system is proposed, which takes the balance of line passing capacity as the constraint and the most economical as the goal. Combined with the case of improving the imbalance of passing capacity between Besi and Betrawati section of Jiga Highway, the concrete operation process is explained. Finally, an evaluation model based on variable weight and grey relational degree decision is constructed for the comprehensive evaluation of large scale systems. On the basis of the combination of subjective and objective weights, the model can comprehensively consider the quantitative and qualitative evaluation indexes and complete the scientific and comprehensive evaluation.
