【摘要】：随着国家经济的发展和居民出行需求的增加,铁路线路投产里程不断增加,高速铁路发展迅速,普速和重载铁路的建设也使路网结构更加完善。其中,工务段作为铁路运输系统中基础管理与基础设施维护兼顾的部门,对保障铁路运输的安全、高效、经济具有十分重要的作用。新线的大量开通要求重新调整工务段的设置方案和管辖范围,同时技术装备水平的提升和高速铁路线路维修养护方面的新特点又对工务段的管理方案提出了新的要求。为解决新线开通对工务段布局优化提出的新问题,本文以工务段与管辖线路为研究对象,提出了新线条件下优化工务段管理方案的方法,并选取典型工务段及线路进行了实例分析。主要内容如下:(1)分析了现阶段我国工务段布局与已开通线路的基本情况。根据现有统计数据,将工务段按管辖线路里程、线路类型等因素进行总结分类,归纳出我国现阶段工务段发展与管理规律,提出先从中观层面确定工务段设置数量与位置,再从微观层面确定工务段管辖范围的工务段管理方案优化流程。(2)将新线条件下工务段设置数量与位置问题抽象为工务段设置渐进覆盖模型,根据工务段的管理特点,以管理水平最大化、固定投入最小化为目标,构建工务段设置渐进覆盖模型,并利用遗传算法进行求解。(3)设计了基于乘法加权Voronoi图的工务段管辖范围确定方法。首先,分析影响工务段管辖的具体因素;其次,利用不同方法确定影响因素的权重,并构建权重修正模型对权重进行修正;最后,利用乘法加权Vornoi图,采用增量算法生成工务段管辖范围图与管辖线路的管理方案。(4)运用本文提出的方法,对“张唐铁路”开通后北京铁路局的工务段布局进行优化,并与实际情况进行对比分析,结果表明本文提出的理论及方法能够较为合理地对工务段的管理范围与线路分割管理方案进行确定。基于此,进一步运用本文提出的方法对未来开通的“京沈高铁”的工务段管辖方案进行规划,为新线条件下工务段的管理方案优化提供参考。
[Abstract]:With the development of national economy and the increase of residents' travel demand, the mileage of railway line is increasing continuously, the high-speed railway is developing rapidly, and the construction of common speed and heavy haul railway also makes the road network structure more perfect. As the basic management and infrastructure maintenance department in railway transportation system, the public works section plays an important role in ensuring the safety, efficiency and economy of railway transportation. A large number of new railway lines need to readjust the setting scheme and jurisdiction range of the public works section. At the same time, the upgrading of the technical equipment level and the new characteristics of the maintenance and maintenance of the high-speed railway line put forward new requirements for the management scheme of the works section. In order to solve the new problem of optimizing the layout of public works section when the new line is opened, this paper takes the public works section and the competent line as the research object, and puts forward the method of optimizing the management scheme of the public works section under the condition of the new line. The typical public works section and line are selected for example analysis. The main contents are as follows: (1) the layout of the public works section and the basic situation of the lines have been analyzed. According to the existing statistical data, this paper summarizes and classifies the public works section according to the factors such as line mileage and line type, sums up the development and management law of the public works section at the present stage in our country, and puts forward that the number and position of the public works section should be determined first from the middle level. At the micro level, the optimal flow of the management scheme of the section is determined. (2) the problem of the number and position of the section is abstracted as the gradual overlay model of the section under the condition of the new line, and according to the management characteristics of the section, In order to maximize the management level and minimize the fixed input, the incremental coverage model is constructed and solved by genetic algorithm. (3) the method of determining the jurisdiction range of public works segment based on multiplicative weighted Voronoi diagram is designed. First, analyze the specific factors that affect the public works section jurisdiction; secondly, use different methods to determine the weight of the factors, and build a weight correction model to modify the weight; finally, use multiplicative weighted Vornoi diagram, The incremental algorithm is used to generate the scope map of the public works section and the management scheme of the jurisdiction line. (4) by using the method proposed in this paper, the layout of the public works section of Beijing Railway Administration after the opening of "Zhangtang Railway" is optimized, and the comparison with the actual situation is carried out. The results show that the theory and method presented in this paper can reasonably determine the management range of the public works section and the scheme of line division management. Based on this, this paper further uses the method proposed in this paper to plan the management scheme of the future "Beijing-Shenyang high-speed railway" section, which provides a reference for the optimization of the management scheme of the public works section under the new line conditions.
