| 摘 要： | 在公路桥梁中,预应力混凝土梁适用于40m以下的中小跨度,50m以上的跨度大多由钢梁占据。文章认为,如果采用诸如提高混凝土跨度、减轻混凝土自重、优化断面和改变梁的体系等措施,可以将预应力混凝土梁的跨度提高到50~70m。

| Abstract: | In highway bridges, prestressed concrete beam was applied to 40 meters below the small and medium span, span 50 meters above most of the beams occupy. This paper points out that, if adopted such as improving concrete span, reduce weight, optimization of concrete section and change the beam system and other measures, can improve prestressed concrete beams with span to 50~70 meters. |
