【摘要】：研究目的:鉴于我国铁路特别是艰险山区铁路的大量修建,建设施工的风险也增大,而控制风险的源头在于设计。铁路设计经过多年的发展,更加注重工程的安全性、可靠性、低风险性、经济性。本文研究了玉溪至磨憨铁路前期工作选线设计,提出了各设计阶段的选线思路。研究结论:(1)玉溪至磨憨铁路地形起伏大,地质条件复杂,风险较高,通过大量的方案综合比选,使线路从热泉低温带穿过,活动断裂对工程的影响小,隧道风险大大降低,为以后的设计打下了坚实的基础;(2)不同的铁路项目,其选线的风险是不同的,应根据项目具体分析风险选线的原则,从设计过程分析,地质与风险综合选线在预可研阶段以宏观分析判断为主,应以区域地质资料结合现场调研情况拟定重大风险选线原则,从而指导选线设计,可研阶段要进一步查明地质条件并对重大地质风险进行验证,有必要进行地质专题研究,初步设计和施工图阶段要落实工程措施;(3)本文的研究可对其他高风险铁路工程选线设计提供一定的借鉴意义。
[Abstract]:Aim: in view of the large number of railway construction in our country, especially in difficult mountain area, the risk of construction also increases, and the source of risk control lies in the design. After years of development, railway design pays more attention to safety, reliability, low risk and economy. In this paper, the route selection design of Yuxi-Mohan railway is studied, and the train of thought for each design stage is put forward. The conclusions are as follows: (1) the Yuxi-Mohan railway has large terrain fluctuation, complex geological conditions and high risk. Through comprehensive selection of a large number of schemes, the line passes through the low temperate zone of the hot spring, and the active faults have little impact on the project. The tunnel risk is greatly reduced, which lays a solid foundation for the future design. (2) the risk of route selection is different in different railway projects. According to the principle of risk selection, according to the principle of concrete analysis of the project, from the analysis of design process, the comprehensive route selection of geology and risk is mainly based on macro-analysis and judgment in the stage of pre-research. The principle of major risk line selection should be drawn up based on regional geological data combined with field investigation, so as to guide the route selection design. At the stage of research, geological conditions should be further identified and major geological risks verified, and it is necessary to carry out special geological studies. Engineering measures should be implemented in the stage of preliminary design and construction drawings; (3) the research in this paper can be used for reference to other high-risk railway projects.
