摘　　要：通过统计与分析深圳市地铁二期工程在建设期所发生的安全事故,发现坍塌是地铁工程建设期间的多发事故,地铁工程在基坑工程、盾构推进、隧道暗挖和高支模施工的过程中易发生安全事故。结合地铁建设过程中的主要工法,通过进一步分析,发现对辅助工法施工重视不够,临时承重结构施工时抢工期常常是引发事故的重要原因。结合工程事故的分析及建设管理经验,提出事故预防的重点,以期为下阶段大规模的地铁工程建设活动提供安全管理经验。By the statistics analysis of safety accidents in Shenzhen Subway Phase Ⅱ Construction, this paper detected that collapse accidents were the accidents most likely happening during construction, and the accidents were prone to happen in the process of foundation pit engineering, shield propelling, underground tunneling and high-formwork construction. By combining with the main methods of subway construction process, this paper showed that auxiliary methods and the temporary bearing structures were the basic reasons for the accident, and put forward the key points of the accident prevention through analysis of the engineering accidents and the construction management experience, which could provide the security management experience for the next subway construction safety.
