Abstract
The invention discloses a method for detecting service performance of a tunnel lining based on defect characteristics of the tunnel lining. A tunnel, an external load and stratum conditions are simulated by establishing a model using a model test method. A structural stress failure test for the model is carried out, and test results of the defect characteristics of a simulation lining of the model are recorded. A corresponding relationship between the defect characteristics of the simulation lining and the remaining bearing capacity interval is established according to the recorded test results. Detection results of defect characteristics of the tunnel lining are recorded using an in-situ detection method, and a remaining bearing capacity interval of the tunnel lining is determined based on the detection results according to the corresponding relationship between the defect characteristics of the simulation lining and the remaining bearing capacity interval of the model.
