The influence of the tunnel construction defects on the tunnel stability is one of the important research problems. This thesis would take the tunnel project in Liaoning as an example to analyze the influence of the tunnel construction defects on the tunnel stability. Models with the hole in different range are carried out to study the influence of the tunnel construction defects on the tunnel stability. On the basis of the model test results, the thesis makes the numerical simulation analysis. According to the model test and numerical analysis, models with the different range hole are different in damage trend. The thesis puts forward some construction defect prevention measures for the tunnel project.
