Back Analysis for Mass Parameters of Tunnel Surrounding Rock

Kai Cui, Xue Kai Pan

Abstract

Tunnel engineering information construction has been widely used, and the back analysis is its core. As the common useful method, displacement back analysis is of special advantages. This paper introduces the calculative method based on the application in a railway tunnel. The result shows that strain softening model can be used to simulate the large deformation mechanism of surrounding rock.
