Abstract

In today's society, high-speed railways, as an important component of modern transportation, have rapidly developed globally due to their safe and fast characteristics. As a crucial supporting structure in high-speed railway engineering, the design and construction of pile foundations directly affect the quality and efficiency of the entire project. Based on this background, this article provides an in-depth analysis of the application and optimization measures of pile foundations in high-speed railways. The study first outlines the types and materials of pile foundations, including common types such as friction piles, compression piles, and composite piles, as well as the application of traditional and new materials. Subsequently, the article elaborated on the design principles, processes, and construction techniques of pile foundations in high-speed railways, emphasizing the importance of safety, economy, and sustainability. In terms of optimization measures, the article proposes four main suggestions. Firstly, adopting efficient pile types and layouts can effectively improve engineering efficiency and reduce unnecessary costs. Secondly, the application of high-performance materials can enhance the bearing capacity and durability of pile foundations. Thirdly, strengthening construction process monitoring is a key step in ensuring construction quality. Through real-time monitoring and data analysis, problems can be identified and resolved in a timely manner. Finally, improving construction safety not only protects the health of workers, but also ensures the quality of the project. Through these optimization measures, not only can the overall performance and safety of high-speed railway engineering be improved, but significant benefits can also be brought in terms of economy and environmental protection.
