Abstract
Recently interest in enlargement of existing tunnel located in downtown or mountain area have been considerably increased along with requirements and discussion on the road-widening. Therefore, it is necessary to study the construction method and stability of tunnel to enlarge the existing tunnel in design. In this study, the design concept on the alignment, excavation method, reinforcement to enlarge the existing tunnel is described on the basis of the enlargement of 2-lane road tunnel under construction. This paper suggests a proper design method for the enlargement of an existing tunnel in useful practice.
