| Abstract: | The tunnel structure settlement monitoring of existing subway operation lines is a necessary method and means to understand and master the tunnel structure deformation,timely detect the disease and judge its safety condition.Combining with the tunnel structure settlement monitoring examples of two operating lines in Beijing subway,this paper discusses the settlement of tunnel settlement under different processes,different burial depths and different hydrogeological conditions,and investigates the necessity of tunnel structure monitoring,in order to guide the maintenance of subsequent tunnel structure. |
