Abstract
Taking the deep foundation pit project of a bus hub in Xiamen as an example,on-site monitoring methods are used to analyze the influencing factors of foundation pit excavation on the deformation of the underground subway tunnel,and to explore the effectiveness of selected construction protection measures such as dynamic dewatering of the foundation pit,water bag back pressure,and balanced soil unloading.The results showed that by comprehensively adopting the above protective measures,the upward deformation of the tunnel was effectively controlled,achieving the goal of protecting the safety of the underground subway tunnel.关键词
