Abstract:

The multiphase driving method for tunneling is conventionally considered as the unavoidable approach for large-size underground constructions and the limitation of equipment. Currently, this approach is adjusted to be an option which can be implemented for economical analysis. In this study, discrete simulation is conducted for analyzing the productivity with various multiphase driving options. The case study, which uses information of on-site available equipment, is implemented for Đèo Cả tunnel with phase division options are proposed and simulated. Result from case study reveals that the multiphase driving with the plan that the face is equally devided can boost the velocity of tunneling compared to the full-phase method. However, the uncertainties in the candidate options are the critical factor for the decision making process. Keywords:?tunnel, underground, discrete simulation, excavated speed, drill and blast
