摘　　要：包西铁路延安至延安北之间既有线改建路堑边坡出现错台、裂缝等病害,为避免施工过程中发生次生灾害,不影响既有线运营。通过对现场勘察及病害产生的原因分析后,采用于路堑顶设置抗滑桩与疏排地下水相结合的方案,在保证施工过程边坡稳定的前提下,有效解决了病害问题,工程成功实施对铁路运营提供了切实的保障。The diseases of dislocation and cracking occurred once on the railway cutting slope of a reconstruction project for existing Yan＇an-Yan＇anbei Line of Baotou-Xi＇an Railway. And then, in order to avoid secondary disasters during construction, and to ensure operation safety of existing line, after the site investigation and analysis on the causes of diseases, the scheme of anti-slide piles at the cutting top with groundwater drainage was used in the treatment works. With this scheme, the diseases on the railway cutting were treated effectively under the premise of slope stability. The successful implementation of the project can serve as a practical safeguard for railway operation in future.
