摘要： 由于具有突发性、危害性大等特点，崩塌落石病害一直为山区既有线路病害防治中的重点。以既有襄渝线王家沟隧道工程为背景，在既有线崩塌落石病害采用棚洞结构进行防护方面做了一些新的尝试，解决了既有线与临近增建二线相邻且间隔较大条件下崩塌落石病害防护工程综合设计技术问题，可为我国山区铁路崩塌落石灾害防护治理工程提供有益的参考和借鉴。

Abstract: Rockfall is a serious geological hazard in railways in the mountainous areas and it is important to minimize the occurrence of the rockfall incidents since it has the characteristics of sudden and large damage scale. This paper presents the rockfall prevention project for a rockfall shelter for the portal of Wangjiagou Tunnel in XiangYu Railway Line. The design improvement was made on the rockfall shelter in an area with known rockfall hazards. The innovative design made an efficient rockfall shelter protecting both the existing railway line and the proposed line with a large distance.
