摘　　要：随着我国高速铁路的大规模建设,地裂缝对高速铁路的影响逐渐显现,成为一种设计与施工须考虑的新型地质灾害,制约着高速铁路的快速发展。汾渭地堑地裂缝十分发育,大西客专穿越地裂缝没有成功经验可借鉴,该工程建设须突破这一技术瓶颈。本文分析了大西客专沿线地裂缝成因,探讨了降低地裂缝对工程结构影响的思路,给出了地裂缝对高速铁路工程危险性分级标准,确立了"刚柔结合、适应变形、预留调整、防治并举"的对策,并推荐了桥梁、路基跨越地裂缝可采取的具体工程措施。As high speed railway is appfied on a large scale in China, ground fissure has become an increasingly challenging defect, which left untreated in project design or engineering construction, could prevail as a new geological disease that restrains the rapid development of the country＇s HSR. Ground fissure, a major defect in the graben area along the Fen and Wei rivers ,poses a technical bottleneck for the construction of Datong-Xi＇an passenger-dedicated railway, with no successful example to learn from. The paper looks into the formation of such fissures and explores ways to overcome the defect influence to the project, while it provides the HSR criteria to evaluate the risks of ground fissure. On this basis, the paper proposes the application of both rigid and non-rigid materials, the adaptation to the deformation, as well as the integration of both precaution tailored for bridge and subgrade enwineerin as well and afterward adjustment, while specific measures are
