Development of a Blast and Fire Resistant Structural Tunnel Liner

The research effort will initiate with a literature review of blast and fire resistant tunnel systems and examination of the existing case studies on past events. The scope of demands to be considered will be determined through preliminary analytical evaluations of a set of tunnel types subject to a range of demands (i.e., small/large Improvised explosive device, vehicle fire / fuel transport vehicle fire). Preliminary designs developed based on first principles and current state of the art will be numerically evaluated under the range of load expected. Numerical models will be verified using case study data. The designs will be refined using parametric evaluations. Preliminary experimental investigation of the prototype liner will be conducted to verify resistance to close in blast and fire exposure. Testing will be conducted at facilities available at Lehigh University and Colorado School of Mines. Based on preliminary results designs may be altered to enhance performance and final verifications will be experimentally conducted. Cost and construction efficiencies will be incorporated during the development phases.
