【摘要】：复杂艰险山区线路总体设计工作是一项复杂的系统工程。一方面线路方案选定是一件关系到全局的总体性工作,综合性强,牵涉面广,涉及到多学科的综合应用,本身就是一项复杂的工作;另一方面复杂艰险山区中地质灾害频发,且灾害成因复杂多变,之间又相互作用,为线路建设增添了巨大的难度。因此,复杂艰险山区线路设计很难用简单的方式进行,应该从系统角度出发进行总体设计,统筹处理好各专业间、整体与局部间的协调关系。通过吸取其他学科总体设计的成功经验,结合已有的研究成果,并以参研的“高海拔大高差艰险山区铁路综合勘察与总体设计理论及工程应用研究”课题为依托,本文规范化了复杂艰险山区线路总体设计的作业程式,认为应该强调三阶段的设计流程:子系统划分、子系统优化和大系统综合评价,并根据线路工程的特点,针对各阶段分别提出了相应的定量化研究方法。首先,针对子系统的划分,总结了线路工程按区间段或不同专业划分子系统的传统方法,随后提出从灾害角度出发,将复杂艰险山区线路工程系统划分为承灾体子系统和致灾体子系统,并采用ISM定量化分析方法,对滑坡致灾子系统进行了进一步的分解作业。其次,在对承灾体子系统进行优化时,采用了一种特别适合解决多种因素间相互作用问题的方法一相互作用矩阵法,考虑各子系统间相互作用的同时将其作用强度定量化。并以通过八渡滑坡工点的线路方案比选为例,详细说明了该方法在优化线路工程子系统时的具体操作。在对区间段子系统进行优化时,提出了一种以保证线路通过能力均衡为约束、经济最省为目标的线路区间段子系统优化程式,并结合改善吉加公路Besi至Betrawati段通过能力不均衡的案例,说明了其具体操作过程。最后,在大系统综合评价时,构建了一种基于变权和灰色关联度决策的评价模型。该模型能够在主客观权重结合的基础上,综合考虑各定量和定性评价指标,完成科学全面的评价,随后以川藏铁路然乌-玉普段四个通过方案评价比选为例进行了实例分析。
[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.
