The mountain route selection of high speed railway concrete operations remain in the project experience level, for the route scheme of the decision making process in the emerging problems, lack of scientific means of settlement. Extenics theory is to explore the rules and methods of solving contradictory problems.The extension and mountainous high speed railway route selection technology is combined with the route selection process formalization, logic and mathematics.Because this is our predecessors did not begin the work, the lack of corresponding research foundation, so the main purpose of this paper is examined in theory, in order to establish the extension of line selection technology basic theory and basic techniques, and combining the Guangdong-Hainan railway and ChenDu-GuiYang railway, through fault zone circuit route design makes the preliminary discussion.The first part introduces the course of development of Extenics theory and railway route selection present situation, then in detail introduced the matter-element, extension, extension method, matter element transformation, composite transform and the transforming bridge method concept.According to the design of railway routes from macro to micro order, in the feasibility study stage introduces the implication system and the application of displacement transformation; in the corridor selection stage combined into ChenDu-GuiYan railway route selection design introduced the divergent tree and the transformation application in ChenDu-GuiYan railway;local alignment phase introduced intermediary transformation, conversion method application in bridge; space alignment stage introduces the divergent tree and related network method applied in engineering design stage; individual introduced divergent tree in ChenDu-GuiYan railway Bijie to Guiyang department application and transform, the expanding and shrinking transformation should be used; in the transport organization stage introduced the split-combination chain method, additions and deletions to transform and application.lt is concluded that in railroad choosing route corresponding to different stages of matter element transformation of corresponding levels and reference transform method and the extension theory is applied to design of railway lines reference step.The Second part introduces railway location is the source of the fundamental measures to reduce earthquake disaster. Firstly, in light of curve through the fault zone, a calculation formulation of plane reserving deformation of the line is deduced based on rupture surface dislocation displacement, steering angle line and the included angle between rupture surface and the line side of the dislocation. When the steering angle line can not be choice, the formation can be directly applied to the calculation of reserving deformation; when the steering angle line can be choice, the best value method for the steering angle to reduce the waste quantities is deduced. Secondly, in light of straight line across the fault zone, this paper analyses the reconstruction amount according to the original design under the difficult condition and puts forward a line repair program at the cost of reducing speed as a reference for comparison and selection of mitigation options. Lastly, the paper discusses the precautions in the repair of circuit design in vertical section and cross-sectional design.
