摘要
分析跨度 2 0 m、宽度 1 .2 m、双拱门式新型断面预应力混凝土空心板桥采用 C80高强混凝土和 1 860级高强低松弛预应力钢绞线其整桥静载和动载试验情况。结果表明 ,试验桥在静载作用下的控制截面混凝土应力和跨中挠度。
The experimental study on full bridge composed with high-performance prestressed concrete hollow slabs has been carried out. These slabs are made of C80 concrete and high-strength Grade 270 strand, with width of 1.2 m and a new type of section. The slow test is carried out to measure the concrete stress of design control section and the bridge deflection. The dynamic test is to measure the dynamic properties of full bridge. It is conformed that the test results are good agreement with the theoretical analysis.
