实心板板梁一般用在跨径小于8米的小桥中,在跨径大于10米的桥梁中,一般用空心板、箱梁等。因为大跨径的桥梁用实心板、不能充分利用材料的特性,因此,几乎没有采用大跨径实心板梁桥的先例。但在某些特殊情况下,往往既需要大跨径又对桥梁的建筑高度有所限制,人们经常采用缩小跨径或采用钢箱梁来解决问题。能否利用高标号混凝土和预应力钢绞线的特性,用实心板梁以达到更好的效果?北园立交是山东省济南市最大的立 Solid slab beam is generally used in small bridges with a span of less than 8 meters. In bridges with a span of more than 10 meters, hollow slabs and box girders are generally used. Because of the solid slabs of long span bridges, which take advantage of the material’s properties, there are few precedents for the use of long-span solid slab bridges. However, in some special cases, both the long span and the height of the bridge are often limited. People often adopt narrowing of span or use of steel box girders to solve the problem. Can use the characteristics of high-grade concrete and prestressed strand, with solid plate and beam to achieve better results?
