Abstract: 기존의 연속형 프리플렉스 합성형교는 사하중과 활하중에 의해 발생하는 부모멘트 구간의 바닥판 콘크리트에서의 인장응력을 감소시키기 위해 내측지점을 1회 상승 및 하강시켜 압축응력을 도입하였다. 그러나 이 시공방법은 지점을 하강시키고 난 후에 정모멘트 구간의 바닥판 콘크리트를 타설하므로 이로 인한 인장응력이 1회 지점 상승에 의한 부모멘트 구간 바닥판 콘크리트와 정모멘트 구간 하부 콘크리트에 도입된 압축응력을 감소시킨다는 단점을 가지고 있다. 본 발명은 이러한 압축응력의 감소량을 추가로 보충시키고자 1차 지점 상승 후 전 구간에 바닥판 콘크리트 두께의 일부를 타설함과 동시에 2차로 지점을 다시 상승시켜 정,부모멘트 구간의 인장측에 유리한 압축응력을 추가로 도입시키는 시공법이다. 본 발명에 의해 부모멘트 구간 바닥판 콘크리트에는 기존의 방법보다 압축응력을 더 유리하게 도입시킬 수 있으며 지점 하강시 1차 상승량보다 하강량을 적게 하므로 정모멘트 구간의 하부 케이싱 콘크리트에 압축응력을 추가로 보충시킬 수 있는 또 다른 장점을 갖고 있다. 이러한 장점을 갖는 공법을 도입하므로 기존의 방법보다 재료의 절감 또는 형고 감소효과를 얻을 수 있다.
