Abstract: The suurrounding rock deformation of highway tunnel is an important index to assess its stability and economy of support structule 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 pledicate the surrounding rock deformation．According to the surrounding rock deformation characteristic of Yangzong highway tunnel，this paper sdopts the nerve network technology to predict the subsidenee displacements．The research results show this prediction method is simple and effective．
