Abstract

In current, there has not been the evaluation model for the optimum design of the multi-utility tunnel by considering urban type and size, the function of surrounding road and feasibility analyses with respect to construction method, and arrangement of accommodation facilities inside multi-utility tunnel. Thus, in this study, we developed the evaluation model for the optimum design of the multi-utility tunnel before and after the decision of the multi-utility tunnel installation. In this paper, we have selected the Deming cycle which is used in various fields among several decision methods for optimizing the design. For the purpose of reflecting the various factors in the design of the multi-utility tunnel, 11 higher indicators were set up to lead to more detailed approaches. In addition, based on the "Plan-Do-Check-Action (PDCA)" circulation method, we can realize the installation of the multi-utility tunnel and design more efficiently through the first phase for conception and the second phase for optimization, and develop the program for the evaluation model accordingly.

현재 도시형태나 규모, 주변 도로기능이나 공동구 건설형식에 따른 타당성 및 경제성 평가 방법, 공동구내 수용시설물의 최적 배치 등을 고려한 공동구 설계 평가모델은 개발되어 있지 않다. 이에 본 연구에서는 도심지 공동구 도입결정과 도입 결정 이후 적용할 수 있는 공동구 최적 설계를 위한 평가모델을 개발하였다. 이를 위해 본 논문에서는 여러 개의 의사결정 방법 중 다양한 분야에서 사용되고 있으며, 직선의 방식이 아닌 순환의 방식이 적용 가능한 데밍사이클(Deming cycle)을 선정하였다. 공동구 도입과 설계시 다양한 인자의 반영을 위하여 11개의 상위지표를 설정하여 보다 구체적인 접근을 유도하였다. 또한 Plan-Do-Check-Action(PDCA)의 순환 방식을 기반으로 1차 구상단계, 2차 최적화 단계를 통한 공동구 도입과 설계를 보다 효율적으로 구현할 수 있도록 하였으며, 이를 위한 최적화 평가 프로그램을 개발하였다.
