摘　　要：采空区是常见的地质灾害。随着城区建设的发展,越来越多的远郊厂矿用地纳入到城市建设用地的范围,面临的采空区问题也越来越多。城市轨道交通工程中遇到采空区一般采取绕避或主动的地基处理方案。根据采空区的特性,在确保运营期安全的前提下,分析了城市轨道交通工程设施的规划及实施要求,提出了主动处理和被动应对相结合的处理思路,从而降低工程难度和工程投资。The gob area is a common geological disaster.With the development of urban construction,more and more remote suburban factories and mining land are planned to be the urban construction land.Thus,urban rail transit construction may encounter more and more gob areas.Once a planned urban rail transit route meets the gob area,it will generally take the passive response to bypass the gob area or take the proactive ground treatment.According to the characteristics of the gob area,the treatment combining proactive treatment and passive response is proposed to reduce the construction difficulty and the investment of the project under the premise of ensuring the safety during the operation period.
