Innovative Foundation Alternative for High-Speed Rail Application

High-speed railway (HSR) provides a fast and robust travel choice that enhances transport of people and goods, which may act as the national economy's main artery. Compared to conventional railways, HSR has more stringent structural and geotechnical requirements to minimize deformations and avoid excessive vibrations. Bridges are a key component of the HSR infrastructure because it can avoid the interruption of existing roadways and the occupation of land. Several foreign countries including Japan and China have developed a standard design for the HSR infrastructure which stands as a great design reference for future projects within the United States. The main goal of this study is to compile and synthesize the existing and ongoing efforts for HSR bridge systems and understand the approaches to provide potential solutions to new design and construction. As a part of this effort, extensive literature review was performed to compile the modeling techniques for various HSR systems and identify common practices. A prototype HSR system model was developed for study. Due to the lack of a complete design guideline for a full HSR model, a train system, train-track system, and soil properties from separate studies are combined under the assumption that they are compatible. Static and dynamic analyses are demonstrated for a variety of train loading scenarios, and the data is used to analyze the behavior of the HSR superstructure. The analysis showcases some of the capabilities associated with the developed numerical model.
