③ 摘要
在亞利桑那州施工的新型Tempe Town Lake大橋已經(jīng)進(jìn)入最后施工階段。1530英尺長耗資2150萬美元的大橋?qū)⒂糜赩alley Metro輕軌工程。這座橋包括兩個(gè)鋼管桁架，橫跨Tempe Town湖的南北方向，聯(lián)系了Phoenix和Tempe ,Mesa以及其它臨近的地區(qū)。它在Valley Metro輕軌線的最初的20英里中提供了重要的線路。每一個(gè)桁架要承受磁軌，一個(gè)桁架通向一個(gè)方向。Valley Metro鑒于美學(xué)、剛性和強(qiáng)度選擇了鋼管桁架的形式。
這種管桁架截面是三角形橫截面，它在幾何形式上補(bǔ)充了附近三座大橋：兩座混凝土拱形橋和一座1912年建成的歷史悠久的矩形截面的鐵路橋。這種新型輕軌橋僅占用了Union Pacific Railroad.鐵路橋的50英尺


Construction of the innovative Tempe Town Lake Bridge in Arizona has reached final stages.Measuring1,530 feet long, the ＄21.5 million bridge will serve the Valley Metro Light Rail Project. Consisting of two steel pipe trusses, the bridge crosses north-south over Tempe Town Lake, connecting Phoenix to Tempe ,Mesa and other neighboring communities. It provides a critical link in the initial 20-mile Valley Metro light rail line. Each truss carries a track , one truss for each direction. Valley Metro selected a pipe truss design for its aesthetics, stiffness, and strength.
The pipe trusses have a triangular cross-section, which complements the geometry of three nearby bridges: two concrete arch bridges and a historical railroad bridge of rectangular cross section built in 1912. The new light rail bridge resides just 50 feet from the railroad bridge, which belongs to the Union Pacific Railroad
