Paper Title:
Back Analysis of the Elastic Modulus and Horizontal Crustal Stress of Tunnel Surrounding Rock with System Identification Method
  Abstract

Cording to the measured data from the Fenshuiling tunnel of Lingnan freeway, the elastic modulus of tunnel surrounding rock and the horizontal crustal stress are back calculated with the system identification method. The results indicate that it is reasonable and the inversion procedure has stronger adaptive control,good convergent calculation stability,rapid calculation velocity. It shows that the system identification method to back calculate the elastic modulus of tunnel surrounding rock is effective.
