地质选线理论的应用是一个由粗略到细微,由整体到局部,由定性到定量,由模糊到清晰的过程。各种理论方法侧重不同,不同勘察阶段采用最适合的理论方法,往往起到事半功倍的效果。同一种理论,在不同阶段应用时,也存在一定的差异。本文作者在长期从事山区铁路地质选线的基础上,以正在修建的巴达铁路为例,对一些常用的地质选线理论方法进行了归纳和总结,对铁路选线具有较好的指导意义。 The application of geological route theory is a rough to subtle, from the whole to the local, from qualitative to quantitative, from fuzzy to clear process. Various theoretical methods focus on different survey stages using the most suitable theoretical methods, often play a multiplier effect. The same theory, in different stages of application, there are also some differences. Based on the long-term geological route selection of mountainous railway in our country, taking the Bada railway under construction as an example, the author summarizes and summarizes some commonly used methods of geological route selection, which has a good guiding significance for railway route selection.
