九站松花江特大桥静载试验

Dead Load Test of the Songhuajiang Super Bridge in Jiu Zhan

吉林至江密峰高速公路九站松花江特大桥是东北三省生跨跨径最大的预应力混凝土半刚构连续梁结构。通过静载试验表明，箱梁跨中挠度值，混凝土应力值均小于规范值。结构具有一定的整体竖向刚度，满足设计与使用要求。而且具有较大的安全系数。对今后设计此类桥梁提供了依据。

The Songhuajiang super bridge in Jiu zhan is the largest prestressed concrete part rigid continuous beam bridge. The dead load test result of the bridge show that the flexibility value and concrete stress value of the box beam are all less than the standard value.
