Abstract

The three dimensional stress distribution in tunnel set with allowance for relative influence and building sequence is investigated. To complete the task the finite  elements analysis was  used. The values of stress concentration factor and conformities of stress distribution in the «lining – mass» system are estimated. The relative influence of each tunnel in tunnel set with allowance for building sequence is identified.
