High-Speed Railway Bridge and Pile Foundation: A Review

Abstract

High-speed railway is trending in developing countries for economic reasons, mobility in the aftermath of COVID-19, and environmental concerns. The high-speed railway operators continuously improve the operational speed to transport more passengers in less time. However, increasing the train loads at high speed might increase the dynamic loads of bridges and affect their pile foundation. A stiffer railway bridge is mandatory for high-speed train safety and passenger riding comfort. However, a flexible bridge is ideal for responding to earthquakes. Thus, these two objectives are conflicting. This review paper provides a bibliometric review aiming to determine the published studies by year and by country, and to visualize different research trends in cluster maps using the VOSviewer software, summarizing the published research for high-speed railway bridges starting from 1964. The review also extracted information from the latest studies by summarizing some essential objectives, useful methodologies, and notable findings that might be applicable to future studies. In conclusion, there is a need for further research to fill the knowledge gap in the study related to the soil–structure interaction phenomenon considering the performance-based seismic design of a high-speed railway bridge on a monopile foundation in the event of lateral spreading due to soil liquefaction.

A Comprehensive Review of Stone Dust in Concrete: Mechanical Behavior, Durability, and Environmental Performance

“…In addition, to address the research questions posed in this paper, the literature review search was initiated by text data mining and clustering to classify the documents found in a time frame of the last 10 years, with subsequent evaluation of the papers. Conducting a literature review through a bibliometric evaluation is the most suitable way to ensure better quality in the reference lists, besides serving as a tool to statistically evaluate the latest research results of published articles, book chapters, and conference proceedings related to the subject [79][80][81]. With this in mind, using Bizagi Modeler [82], Figure 1 illustrates the sequence of the literature review.…”

“…The performance requirements for choosing search systems should allow queries to be performed, filters to be applied, or citation searches to be managed, with high standards and accessibility of data resources [79]. Before starting the literature review search, one must initially collect relevant documents from multiple sources.…”

Ultimate Load-Bearing Capacity and Sustainable Performance of Pile Foundations of Yanji Suspension Bridge in Fault Zone Based on Refined Geological Model

“…Many researchers have studied a great deal about the mechanical performance of pile foundations in near-fault zones [14]. For the impact of faults on the foundation or overall structure, Bray [15] suggested that when an active fault cannot be avoided, its effects can be minimized through a correct design.…”
