Prediction of Nerve Network on Surrounding Rock Deformation in Tongyu Highway Tunnel

The surrounding rock deformation of highway tunnel is an important index to assess its stability and economy of support structure in NATM.It is a data column which is related with measurement time sequence,so we can set up some effective models and methods to predict the surrounding rock deformation. According to the surrounding rock deformation characteristics of Tongyu highway tunnel, the nerve network technology is adopted to predict the subsidence displacements.The research results show this prediction method is simple and effective.
