摘　　要：不良地质条件是诱发青岛地铁工程事故发生的重要风险因素。根据目前青岛地铁工程建设的数据资料,发现其存在的主要不良地质包括富水砂层、承压水、上软下硬地层、断层破碎围岩和特殊土(填土及软土)等,是青岛地铁建设中安全问题的主要危险源。论文根据常见不良地质问题的分布规律及工程特性,结合地铁生产安全事故实例,提出了不良地质问题的勘察、设计及施工对策,希望对后续青岛地铁工程的勘察、设计和施工过程有一定的借鉴作用,为今后地铁施工不良地质条件的风险控制提供参考依据。Adverse geological conditions are the important risk factors that induce the accidents of Qingdao metro project.According to the current data of Qingdao metro construction,it is found that the main adverse geological conditions include water rich sand layer,confined water,upper soft and lower hard stratum,fault broken surrounding rock and special soil(fill and soft soil),which are the main risk sources of safety problems in Qingdao metro construction.According to the distribution law and engineering characteristics of common adverse geological problems,combined with the example of subway production safety accidents,this paper puts forward the investigation,design and construction countermeasures of adverse geological problems,hoping to have a certain reference for the investigation,design and construction process of the follow-up Qingdao subway project,and provide a reference for the risk control of adverse geological conditions in the future subway construction.
