Structural Deformation Rule and Safety Evaluation of Utility Tunnel in Early Operation Period in Water-rich Soft Soil Area
The underground utility tunnel is the lifeline project of a city.After a long operation period,the utility tunnel located in the special geological environment is easy to produce the structural diseases such as uneven settlement,joint deformation and section torsion,which affect the normal operation of the utility tunnel.Therefore,it is necessary to monitor the structural health of underground structures,to find out the problems before the formation of structural diseases and take the engineering measures to solve the problems so as to ensure the operation safety of underground structures.Based on the underground utility tunnel in Xuwei New District of Lianyungang City,the structural deformation monitoring and disease investigation of the utility tunnel are carried out.The structural health monitoring data are analyzed.The safety state of the utility tunnel is evaluated.And the corresponding maintenance measures are put forward,which provide some reference for similar projects in China.
