摘　　要：地裂缝灾害对铁路安全有严重的影响。铁路路基结构属于土工结构物,具有一定的柔性,以路基结构通过地裂缝灾害区域相对桥梁等其他结构具有更大技术优势。根据地裂缝灾害的性质和分级研究提出地裂缝地段路基工程各种处理措施,并对各种措施的适用性进行了阐述,建议采用综合处理的方式,供地裂缝地段铁路路基的设计和施工参考。Ground fissure disaster seriously endangers railways. Railway subgrade is a earth structure with certain flexibility, hence, for the area subject to ground fissure disaster, it has more technical advantages than bridge and other structures. According to the character and classification of ground fissure, various control measures for the subgrade engineering in such area were proposed; and then it was suggested to adopt comprehensive control after explanation of each measure＇s applicability. It may provide a new train of thought to the design and construction of railway subgrade passing though active ground fissure area.
