Research on the Load Test of Reinforced Concrete Tied Arch Bridge after Strengthening and Improving Load Level
Aiming at a half-through reinforced concrete tied arch bridge,this paper evaluates its overall bearing capacity,working performance and operation safety under the condition of strengthening,improving load level and operating for many years through load test.Research has found that the overall structural stress of the bridge meets the requirements of the design load highway level Ⅱ and pedestrian load of 3.5 kN/m2,but the repair work of the hanger rod and transverse beam must be carried out in time.
