本文分析了铁路工程的主要结构单元，如路堤、桥涵、边坡、隧道等工程的属性，认为铁路工程主要是地质工程．从而提出地质工程理论是加快铁路建设的基础理论，及其相应的两项主要应用技术，即：（1）地质勘察和预报；（2）地质改造．对上述两项应用技术作了阐述，并提出几点建议。 This paper analyzes the main structural elements of railway engineering, such as the properties of embankments, bridges and culverts, slopes, tunnels and other projects, that the railway project is mainly geological engineering. Therefore, the theory of geological engineering is put forward to speed up the basic theory of railway construction and its corresponding two main application technologies, namely: (1) geological prospecting and forecasting; (2) geological reconstruction. The two application techniques described above, and made a few suggestions.
