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.
