景觀公路、棧橋、加勁擋土牆、地工與環境景觀之融合
摘要
美國科羅拉多州I-70 Glenwood Canyon段穿越峽谷,環境敏感、風光秀麗,加上怒濤洶湧的科羅拉多河貫穿其中,是美國高速公路系統中最後完成的一段,也是全美聞名的景觀道路。
I-70 Glenwood Canyon段採取了多項與環境、生態與景觀相融合的新技術,包括:雙階棧橋、加勁擋土牆、雙T型擋土牆、預力懸臂式橋面版、預鑄節塊橋樑、隱藏式地錨錨頭、落石防護系統、自然相結合的休息區、智慧型隧道系統、假隧道、生態廊道與環境相容的岩面染色等,對環境、景觀與生態之助益頗大,值得吾人借鏡。
英文摘要
I-70 Glenwood Canyon, a wandering scenic highway along the roaring Colorado River, is the last link of the interstate highway system in the U S A. To reduce environmental impact due to highway development, the Colorado Dept. of Transportation (CDOT) has taken a series of action to alleviate damages of environment, landscape and ecology of the beautiful canyon.
The technology used in I-70 Glenwood Canyon project included:terraced viaducts, pecast segmental bridges, hidden-head anchors,rockfall protection system, naturalized rest areas, artificially intelligent tunnel, extended tunnel portals, ecological crossing for animals, rock fa?ade painting, etc.
