Load Test Design and Stability Analysis of Basket Handle Arch Bridge with Reinforced Concrete

Abstract

Basket handle arch bridge with reinforced concrete shortens the distance between the arch rib compared with parallel arch rib bridge, improves the lateral stability, predecessors have done a lot of research on basket handle narrow arch bridge, but the study of wide span arch bridge is insufficient, conduct load test on a wide basket handle arch bridge which 33m wide and mainspan is 90m, the test results show that the large width-span ratio arch bridge has higher bearing capacity, but vertical bearing capacity is not improved, the dynamic coefficient increases when the speed is higher than 30km/h, the measured dynamic coefficient at jumpy driving is relatively large, the dynamic coefficient is significant when jumpy driving speed is 10~15km/h.
