| Abstract: | The stress distributions in the multi-arch tunnels with various lining thickness were analyzed through the finite element method.The factor of safety of the lining structure correspondent to the lining thickness is obtained from the analyses so that the appropriate lining thickness can be selected.These results can be used in the design the similar lining structures for the multi-arch tunnels. |
