③ 摘要
19世紀(jì)40年代后期，預(yù)應(yīng)力混凝土首次引入美國，很快便廣泛應(yīng)用于橋梁結(jié)構(gòu)中。據(jù)記載，美國建筑了數(shù)千座預(yù)應(yīng)力混凝土公路橋。鐵路橋利用預(yù)應(yīng)力混凝土也很普遍。在未來的幾年中，預(yù)應(yīng)力混凝土橋有望繼續(xù)使用和不斷向前發(fā)展

Prestressed concrete has been used extensively in U.S. bridge construction since its first introduction from Europe in the late 1940s. Literally thousands of highway bridges of both precast, prestressed concrete and cast-in-place post-tensioned concrete have been constructed in the United States. Railroad bridges utilizing prestressed concrete have become common as well. The use and evolution of prestressed concrete bridges is expected to continue in the years ahead.
