Zusammenfassung:Disclosed are a method and a device for optimally modelling long-span bridge to review feasibility study on the long-span bridge, capable of reasonably calculating quantities and price to review the feasibility study on the long-span bridge. According to the present invention, the method for optimally modelling the long-span bridge includes the steps of: (a) inputting the expected number of lanes and the expected type of the lanes for the reinforcement of a target long-span bridge for the feasibility study, and inputting an expected main span length of the target long-span bridge; (b) determining final reinforcement type proposed cross section based on reinforcement type cross section specification of match cases where reinforcement matched to the expected number of lanes and expected type is applied, a trend cross section matched to the expected main span length, and a trend geometrical moment of inertia, which are obtained from a long-span bridge design information database storing design information on a plurality of previously-designed long-span bridges; and (c) determining a finally suggested pylon specification, based on cross sectional outline specification of the pylon of the matching cases, a trend effective cross section matched with the expected main span length, and the trend geometrical moment of inertia, which are obtained from the long-span bridge design information database. 장대교량의 사업 타당성 검토를 위한 장대교량 최적 모델링 방법이 개시되며, 본 장대교량 최적 모델링 방법은 (a) 사업 타당성 검토 대상인 대상 장대교량의 보강형의 예상 차로수 및 예상 타입이 입력되고, 상기 대상 장대교량의 예상 주경간장이 입력되는 단계, (b) 기설계된 복수의 장대교량의 설계정보가 저장된 장대교량 설계정보DB로부터 도출되는, 상기 예상 차로수 및 상기 예상 타입에 매칭되는 보강형을 적용한 매칭사례들의 보강형의 단면 제원과 상기 예상 주경간장에 매칭되는 추세 단면적 및 추세 단면2차모멘트에 기초하여, 최종 보강형 제안단면을 결정하는 단계, 및 (c) 상기 장대교량 설계정보DB로부터 도출되는, 상기 매칭사례들의 주탑의 단면 윤곽제원과 상기 예상 주경간장에 매칭되는 추세 실효단면적 및 추세 실효단면2차모멘트에 기초하여, 최종 주탑 제안단면을 결정하는 단계를 포함할 수 있다.
