摘　　要：横断面选线技术在以往铁路工程选线中主要用于地形横坡较陡地段,对地质界面横坡较陡地段考虑不充分。本文提出了地质横断面选线的概念,可适用于地质构造线与线路平行或小角度相交地段、顺河沿溪和横坡较陡地段、顺层地段、不良地质路段和并行既有道路等地段。在总结地质横断面选线适用地段和工作方法的基础上,通过一系列工程案例对地质横断面选线进行了详细说明。工程实践表明,采用地质横断面选线技术可进一步改善铁路工程的安全性、经济性和合理性。In the previous route selection in railway engineering,cross-section route selection technology was mainly applied to sections with steep topographic cross slopes,but was less considered in sections with steep geological interface cross slopes. This paper proposes the concept of geological cross-section route selection,which can be applied to sections where the geological tectonic line is in parallel with or intersects with the railway line at a small angle,sections along the river,sections with steep cross slopes,bedding sections,sections with unfavorable geological conditions,and sections in parallel with existing roads. On the basis of summarizing the applicable sections and working methods of geological crosssection route selection technology,this paper explains the geological cross-section route selection technology in detail by giving a series of project cases. The engineering practice shows that applying the geological cross-section route selection technology can further improve the safety,economic efficiency and rationality of railway engineering.
