摘要


台灣地區坡地面積大地形陡峭平原地區人口密集且都已開發,以國道1號五股至楊梅段拓寬工程C903標泰山林口段工程為例,橋梁橋址經過山坡地基礎於邊坡開挖施工,開挖面臨邊坡穩定處理及開挖擋土支撐,以傳統邊坡穩定處理,將需數月之久,作業空間受限,擋土支撐不易適用土層位於高速公路及大窠坑溪間狹窄腹地,因高速公路邊坡陡峭,而評估由原設計之樁基礎變更為井式基礎之可行性選用之分析。 井式基礎開挖面積小,不須大型設備即可施工,且施工優點適合山區橋樑基礎,突破傳統工法限制。可降低對工址環境及景觀之衝擊,減少大量邊坡及土方開挖橋墩大多位居山坡,具開挖減量、環保減碳、工期縮減、景觀維護、兩種分析模式之探討中一窺究竟。

In C903 of Freeway NO.1 widening project Wugu-Yangmei section, the bridges were constructed along the hillside. It will take several months to excavate and retain by traditional procedure. The working place between the Freeway NO.1 and Ta-Ke-Keng Stream is very narrow, and the hillside along the freeway is on steep slope. The feasibility analysis of selection from pile foundation of original design changing to well foundation is needed. When well foundation is constructed, the excavation area is small, the building equipment is small, and it has well efficiency. It is suitable for bridge foundation along hillside. These two foundations will be compared and evaluated from construction, environmental protection, shorten construction period, and landscape maintenance
