Summary:PURPOSE: A high intensity tunnel segment optimal design method is provided to apply high strength reinforcing bars and concrete of increased compressive strength to a design and prevent excessive reinforcement. CONSTITUTION: A high intensity tunnel segment optimal design method comprises a step of individually calculating design strength on a plurality of concrete-reinforcing bars combinations and a plurality of concrete of different compressive strengths; a step of setting a predetermined safety factor and of individually calculating a required reinforcing bar section on concrete-reinforcing bars combinations; a step of extracting the concrete-reinforcing bars combinations including the required reinforcing bar section smaller than a required section of a standard concrete-reinforcing bar combination; a step of selecting the concrete-reinforcing bar combination including the required section of a minimum reinforcing bar.
