中文摘要本文以新亚欧大陆桥段水害为研究对象,经过深入调查、实地考察和历史资料的收集,应用数理统计和构建模型的方法,从孕灾环境、致灾因子、承灾体等角度详尽研究了陆桥新疆段沿线水害的成因机理和时空耦合关系。分析了陆桥段水害危险性,并加以区划,旨在为西部大开发,建设大通道的防灾、减灾工作提供科学依据。文中创新之处可归纳为以下几点:1. 定性分析与定量相结合。论文注重学科的交叉应用,针对水害事件的突发性、随机性和难预测性等特点,突破以往对资料的收集整理和简单数据处理等传统研究方法的限制,在对陆桥段水害孕灾环境、致灾因子等分析的基础上,科学的运用灰色关联等非线形数学方法构建模型,对陆桥新疆段水害成因机理、时序分布等特性进行了研究和探讨。2.水害时空交叉耦合分析。在对陆桥新疆段近39(1959-1997年)年水害历史资料分析过程中,把时间序列和空间序列有机的结合在一起,通过时空交叉耦合分析,确定出陆桥沿线不同区段水害发生的重点时段,以及不同时段水害发生的重点区段。3. 从系统的角度研究水害事件。基于系统的思想,在提出铁路水害危险度等级划分原则、依据、方法和步骤的基础上,建立了陆桥新疆段水害危险性区划系统,从而丰富了铁路灾害研究的内容与方法。In this paper, take the flood disaster of Xinjiang Line of New Eurasian Continental Bridge as a research subject. After finished the work of investigation, inspection and date-collection, the cause mechanism of formation, dynamics characters and time-spatial regulation of the flood disaster of Xinjiang Line of New Eurasian Continental Bridge have been analyzed in the aspect of hazard-formative, hazard-formative factors and hazard-affected bodies by making use of Grey relative and Model Analysis. On the basis of theory analysis, the dangerous-degree division of sections of Xinjiang Line of New Eurasian continental Bridge has been determined regarding the events of flood disaster, which occurred in the past 39 years (1959-1997). All the work has been done with the aim to provide theory basis for forecasting hazard, preventing hazard and controlling hazard effetely in order to built road for guaranteeing western exploration. In this paper, the neoteric work are listed as following: 1. On the basis of determining the nature ,fixture quantity has been done. In this paper, limitation to the method of data-collection, settlement and disposition in natural hazard research has been broken through. What has been done is to pu attention to the intersect application of different subjects aimed at the natural disaster characters of random, complexity and paroxysmal. On the condition of analyzing of hazard-formation, hazard-formative factors and hazard-affected bodies, the cause mechanism of formation, dynamics characters and time-spatial regulation of the environment flood disaster of Xinjiang Line of New Eurasian Continental Bridge have been analyzed by using Grey Relative and Model Analysis. 2. Coupling analysis of the time-spatial series of flood disaster, In dealing with the history data of 39 years (1959-1997) of flood disaster of Xinjiang Line of New Eurasian Continental Bridge, put forward the means of coupling. after analyzed by combining the tie series with spatial series of flood disaster, the dangerous period of time of different sections and the dangerous sections of different period of time of Xinjiang Line of New Eurasian Continental Bridge has been determined in the paper. 3. Apply system theory to the flood disaster research. On the condition of system opinion, the sections division system of flood disaster has been established in the study of Xinjiang Line of New Eurasian continental Bridge on the basis of putting forward principle, method, process of distribution system, which enriches the content and method of railway flood disaster.
