Abstract
The relationship between initial displacement and converged one, which has been used to judge the convergence and the time for execution of tunnel supports, is conventionally evaluated to be one linear line. Though, the actual situation of convergence during tunneling is influenced by the bench length. In order to construct tunnel more safely and rationally, tunnel convergence should be predicted accurately and be controlled by tunneling method. In this paper, the effects of tunneling methods to the relationship between initial displacement and converged one are analysed based on the convergence data, measured in the sqeezing rock tunnel. Also, qualitative evaluation using 3D numerical analysis is carried out.
