Abstract：Research purposes: The concrete slab structure is widely used in the lining structure of railway and highway tunnels．Under the long－term pressure and load of the surrounding rock of tunnel，the concrete slab structure is often deformed and destructed to endanger the safe operation． The test and research were done on the characteristics of the deformation and damage of the concrete slab structure to forecast the possibility of accidents and provide the in － situ monitoring and prediction way to guarantee the safe service of the structure．
Research conclusions:The test results show that application of the time series analysis method can achieve the high precision of predicting the concrete slab deformation with the linear fitting correlation coefficients of more than 0.93 in all measuring points and the prediction error of less than 10% . So，this forecast model is available and can be used as an effective method for monitoring the lining structure of tunnel．
