③ 摘要
19世纪40年代后期，预应力混凝土首次引入美国，很快便广泛应用于桥梁结构中。据记载，美国建筑了数千座预应力混凝土公路桥。铁路桥利用预应力混凝土也很普遍。在未来的几年中，预应力混凝土桥有望继续使用和不断向前发展

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.
