Abstract: The Fen-Wei basin is the most serious area of the ground fissure formation in China. Xi'an is located in Fenwei basin and the exposed surface of the cracks and fractures were found concealed in 15. Based on the existing knowledge, the new point about the causation of Xi'an crack is raised. According to the research of Xi'an crack on the current status of activities and its development trends, the cracks in the surface with the largest width and length of metro security is raised on the expert advice and the latest research. The MTR measures to deal with cracks are raised on the analysis of the impact and failure mode on the structure which is caused by the cracks. Based on the existing knowledge and research, analysis of the development tendency of Xi'an cracks and the MTR measures to deal with cracks will contribute to the development of urban underground track

Key words: Xi'an, Xi'an crack, metro tunnel, treatment measures
