Optimization of Reasonable Interval of Parallel Tunnel
To acquire the stress distribution of surrounding rock is the important mean of stability analysis and the major task of numerical simulation. But the breaking probability cannot be expressed by the magnitude of single stress straightly. Based on the Mohr-Coulomb theory, coefficient S was deduced and used for further treatment of the result of numerical simulation. Models of parallel tunnel with different interval were building and analyzed. The different distributions of coefficient S were compared and analyzed after numerical calculation. The more reasonable tunnel interval was given, which can be a reference for optimization of design of similar projects.
