Abstract

With the acceleration of urbanization, the construction of large-scale public facilities has put forward higher requirements for foundation. As a deep foundation treatment technology, the stability and reliability of pile foundation have received much attention. This article systematically studies the types, design principles, construction methods, and their applications in large-scale public facility engineering of pile foundations, aiming to provide theoretical guidance and practical reference for the optimization design and construction of pile foundations. Firstly, this article provides an overview of the research background and significance of pile foundations, compares the current research status at home and abroad, and clarifies the research ob jectives. Next, the standards for classifying pile foundations based on materials and functions were introduced in detail, and the characteristics of different types of pile foundations were analyzed, including bearing capacity, durability, economy, and environmental adaptability. In terms of design principles, the importance of considering geological conditions, load analysis, pile type selection, and pile foundation layout was emphasized. In terms of construction methods, different pile driving methods such as driving method, drilling method, and static pressure method and their quality control points were discussed. Finally, the future development trends of pile foundations were discussed, including the application of new materials, exploration of new technologies, sustainable development and environmental design, as well as international cooperation and standardized development. The research conclusion of this article points out that reasonable selection and design of pile foundations can effectively improve the stability and economy of large-scale public facility projects. At the same time, it also pointed out the shortcomings of current research and the direction of future research.
