철도터널 설계안에 대한 굴진별 사전 위험도 평가 사례

an attempt is made for validating an outcome of tunnel design by checking the variation of KTH-index along longitudinal tunnel section. In KTH-index simulation, it is the most important to determine the input factors reasonably. The design factor and construction condition are set up based on the designed outcome. Uncertain ground conditions are arranged based on borehole test and electro-resistivity survey data. A scenario for ground conditions are set up. From this simulation, it is shown that this methodology could be successfully applied for providing quantitative validity of a tunnel design and also potential hazard factors which should be carefully monitored in construction stage.
