The New Austrian Tunneling Method(NATM) is used to construct the liner in the wide span tunnel with super-shallow embedment and concealed excavation,but it is very important for NATM construction to monitor and measure.By mathematical mechanical analysis of actual measuring data,it can select and correct support parameters to guide construction.It is not only the measures of safety guaranteed,but also the important method of optimizing the structure and reducing the material consumption.
