长系杆钢管混凝土拱桥静载试验

Static Load Test of Concrete-fi lled Steel Tubular Arch Bridge

静载试验是验证桥梁工程结构安全的重要方法,曹娥江袍江大桥为5跨飞燕式钢管混凝土拱桥,大桥建成后通过静载试验对袍江大桥整体结构的安全承载能力和使用条件做出了判断。静载试验测定了结构关键截面的挠度和应变,并建立了桥梁的有限元模型,对不同加载工况进行计算分析,将实际测试值与理论值进行比较。

Static Load Testing is an important method for verifying the structures safety of the Bridge engineering, the Pao river bridge of Caoe River is a concrete filled steel tubular arch bridge which has five-span steel tube of Swallow type, after the completion of the bridge, make a judgment for the safe bearing capacity and service conditions of the Pao river bridge overall structure through the Static Load Testing. Static Load Testing measured the Deflection and the Stain for the pivotal cross-section of the structure, and finite element model of the bridge is established, calculation and analysis the different loading conditions, compare the actual test values to the theoretical values.
