Research and innovation for key technologies of the U-shaped girder overhead system in urban rail transit

On basis of the analyses of application and bottleneck of urban rail transit elevated lines in China, the main research achievements of the author and his team in the development and application of U-shaped girder overhead system were presented in this paper. The achievements included the following aspects: the structure technology of U-shaped girder, noise reduction technology, the integration technology with other rail systems, construction technology, technical economy, etc. By applying the complete theory and computing method on the U-shaped girder structure, a new environment-friendly overhead system in urban rail transit was established, which had some significant advantages, such as vibration attenuation and noise control, energy conservation and environment protection, attractive appearances, powerful deck functions, train safety protections, convenient and short-term construction, project cost control, and so on. The application of U-shaped girder overhead system will lead to a significant contribution to the healthy and sustainable development of urban rail transit elevated lines in China.
