Abstract:	國道1號五股至楊梅段拓寬工程（五楊高架工程）為中山高速公路第二段高架拓寬路段，全長40公里，於2009年11月21日發包動工，完工後可望紓解中山高速公路（中山高）桃園路段長久以來嚴重的塞車問題。五楊高架工程沿中山高兩側拓建，為避開中山高北上側37k至39k之「岩屑崩滑高敏感區」，該區段之五楊段北上線調整布設於南下線側，致北上線須兩度跨越中山高。因此，為避免衝擊既有中山高之交通，兩處跨越橋於中山高內不落墩，須採大跨距之橋型。本研究主要探討五楊高架工程中，林口龜山段北上線工程之林口跨越橋之施工採旋轉工法之決策因素，並歸納出橋梁工程中適用旋轉工法之施工條件。本研究進而分析旋轉工法在工期及成本方面之特性，並與原設計方案之工期及成本進行比較。本研究之成果可供設計單位及施工單位對於大跨距橋梁工程專案，在進行可行性評估以及在選擇施工方法時之參考。 Wugu to Yangmei Freeway widening project is the second widening section of the No. 1 National Freeway, and is expected to relieve the serious traffic congestion in Taoyuan area on the Freeway. This widening project, 40 kilometers in length, mostly elevated bridges and constructed by the Freeway on both sides, was commenced on November 21, 2009 and finished in April 2013. To avoid a "debris avalanche slide highly sensitive area" of the north bound side of the Freeway between 37k+400 to 39k+100, the northern bound section was designed to cross the Freeway to join the elevated southern bound bridge and then cross the Freeway, again, back to the northern bound in that area. In order to avoid impacts on traffic, no piers were allowed in both cross sections thus, long-span bridges are required. This research focuses on a special rotational construction method used for constructing the elevated bridge crossing the Freeway between Linkou and Gueishan in the widening project. Characteristics of the special construction method, such as limitations, duration, and costs were emphasized. The construction duration and costs were compared to that of a different construction method which was originally designed. Special reminders during construction using such a rotational construction method were also concluded. Results of this research can serve as a useful reference for similar projects in the future.
