| Abstrait: |
The main span of railway cable-stayed bridge in China has broken through from 312m in 2000 to 1092m in 2020, with rapid development in recent years. It comes from aspects of new material, new structural form, accelerated bridge construction method, and innovated construction facilities and equipment. New materials mainly include bridge structural steel with higher yield strength, stay cable with higher tensile strength and ultra-high-performance concrete (UHPC), etc. New structural forms refer to three-main truss with three-cable plane, cable-stayed bridge with ballastless track system, multi-pylon railway cable-stayed bridge, etc. Concept of accelerated bridge construction has been also applied in caisson construction, truss girder assembling, truss girder hoisting, etc. Several new facilities and equipment have also been created such as integral bridge expansion joint, hoisting crane, and smart torque wrench, and so on. Challenges have also been discussed. |
