Taking the Caiyuanba Changjiang River Bridge in Chongqing as an example,this paper makes a study of the effect of tilting angle of basket handle arch rib on the stability of the overall arch bridge and gives the rational tilting angle of the arch rib,using the finite element method.

The main span of Yunnan Xiaowan Bridge is designed as a 130 m hingeless cantenarian basket handle arch bridge.

This paper presents the technical considerations of the hybrid system structure of continuous girder and basket handle arch applied to Hanggang River Bridge and analyzes the characteristics of the structural formation,mechanics and construction of such type of the new structure.

The inclination angle of arch rib and the height of concrete-spouting at the arch springing are two important parameters in the design of Steel tube & Con-crete-filled steel tube X arch bridge,they greatly influence the performance of the structure in stable properties and dynamic characteristics.

The CFST has always been adopted in X arch bridges due to its superior properties.

Spatial dynamic property analysis of X-style arch bridge

Half-through X-style arch bridge with steel box girder is employed for the main structure and bolted and welded steel-concrete composite beam for the main girder.

Based on the coupled vibration theory, dynamical models and equations of motion were set up respectively to an X-style arch bridge and vehicles.
