搜集2002—2016年（统计到3月）地铁施工事故246起，从时间、事故类型、施工工法、发生位置、站台形式、死伤人数等8个方面分析、描述事故发生的规律性。结果显示，事故发生的总数呈上升趋势，但每千米死亡人数呈下降趋势；每年1月、5月、7月、11月，每天0:00-1:00、8:00-11:00和15:00-18:00地铁施工事故发生较为频繁；坍塌是地铁施工项目中发生最频繁的事故类型，占43%；明挖法施工数占地铁施工事故的31%；盾构法施工数占区间工程施工事故的62%；火灾爆炸是区间工程施工中较常发生的事故，而在车站工程中发生较少。最后，结合长三角地区主要特点，从技术、管理、政策3方面有针对性地提出对策和建议。

The data of subway construction accidents in China from 2002 to March, 2016 are presented in order to analyze the regularity of these accidents from the perspective of years, months, hours, accident types, construction methods, locations, numbers of deaths and so on. The results show that the total number of accidents is on the rise, but deaths per kilometer gradually decline. Most construction accidents occurred frequently in January, May, July and November every year and during 0:00-1:00, 8:00-11:00 and 15:00-18:00 every day. Collapse is the most common accident type, occupies 43%; Open cut method accounts for 31% of subway construction accidents, and shield method 62% of section construction. Fire and explosion often took place during section constructions while seldom happened during station constructions. Finally, according to the regularity, some countermeasures and the suggestions of subway construction safety are put forward considering the characteristics of Yangtze River Delta region from the three aspects of technology, management and policy.
