With the increase in tunnel construction scale and service time, the serviceability assessment of shield tunnels has become increasingly critical. The single assessment indicator is not detailed. However, the comprehensive assessment indicator is more qualitative and lacks a scientific basis. In response to this problem, an intact and efficient assessment system for shield tunnel serviceability is proposed. This assessment system combines rapid and detailed assessment. The rapid assessment uses the shield tunnel serviceability index to determine the safety level of tunnels. The tunnel needs to be assessed in detail to evaluate the structure's safety, which is at the average level. The detailed assessment includes three parts. The convergent deformation of the tunnel is calculated based on the transverse mechanical model, the joint force is analyzed based on the longitudinal joint mechanical model, and the differential settlement is analyzed based on the theory of beam on elastic foundation. The mechanical state provides a basis for structural serviceability evaluation, disease causes, and disease management. The assessment system is applied to a specific tunnel section of the Guangzhou Metro. It can analyze the tunnel's safety performance and guide maintenance scientifically and efficiently.
