Failure Performance of 3DP Physical Twin-Tunnel Model and Corresponding Safety Factor Evaluation

Quantitative stability evaluation of multi-tunnel structure is an important issue related to the safety assessment and stable construction of geotechnical underground tunnels. In this work, the overall failure process of twin tunnels were exhibited by a physical simulation based on the 3D printing (...
