铁路主要工程地质问题分析及防治

To analyze and prevent main problems of railway engineering geology

地震、滑坡、泥石流等地质灾害和软土、黄土、冻土等各类特殊土对我国铁路的建设和安全运营构成重大威胁,所造成的损失和治理费用也十分惊人。结合近年来大型铁路项目工程实践和重大铁路地质灾害防治经验,对主要不良地质、特殊岩土问题及防治对策进行分析和总结,为研究和解决各类铁路工程地质问题、完善具有中国特色的铁路工程地质技术标准体系提供参考。

Geological disasters, such as earthquake, landslide and mudslide,and kinds of special soil, such as soft soil, loess and frozen soil, have a significant threat to the construction and operation of railways in our country, leading to very huge losses and expenses. With the engineering practice of large railway programs and the experience of preventing major railway geological disasters in recent years, the article does analysis and summary on problems and prevention countermeasures of unfavorable geology and special rock and soil, in order to provide references for researching and solving geological problems of kinds of railway engineering, and perfecting the geological technical standard system of railway engineering with Chinese characteristics.
