Research Progress and Development Trend Analysis of Particle Fragmentation in Large-Sized Subgrade Backfill Materials

摘要: 为系统梳理路基大粒径回填料颗粒破碎领域的研究现状与发展趋势，本文基于Web of Science核心合集和中国知网数据库，运用CiteSpace对相关文献进行计量与可视化分析。从年度发文趋势、核心作者、国家与机构分布、关键词共现与聚类等方面展开研究。结果表明：该领域研究经历了初始阶段、缓慢增长期和快速增长期三个阶段；英文文献发文量最高的作者为Ma Wei，中文文献则以尧俊凯为代表；中国、美国、澳大利亚和日本是研究成果最多的四个国家，中南大学土木工程学院为发文量最高的机构。研究还发现，国内研究热点集中于路基病害、施工技术与建筑垃圾资源化利用等方面，而国外研究更注重力学行为、数值模拟与工程仿真。本文通过对高影响力文献的梳理，进一步总结了颗粒破碎机理、实验方法与工程控制措施的研究进展，以期为该领域的后续研究提供参考。

Abstract: To systematically review the research status and development trends in the field of particle fragmentation in large-sized subgrade backfill materials, this paper conducted a bibliometric and visual analysis of relevant literature based on the Web of Science Core Collection and the CNKI database using CiteSpace. The analysis focused on annual publication trends, core authors, distribution of countries and institutions, keyword co-occurrence, and clustering. The results show that research in this field has undergone three stages: initial, slow growth, and rapid growth. Ma Wei is the most prolific author in English literature, while Yao Junkai is the most representative author in Chinese literature. China, the United States, Australia, and Japan are the four countries with the most research outputs, and the School of Civil Engineering at Central South University is the institution with the highest number of publications. The study also reveals that domestic research focuses on subgrade diseases, construction techniques, and the recycling of construction waste, whereas international research emphasizes mechanical behavior, numerical simulation, and engineering modeling. By reviewing high-impact literature, this paper further summarizes research progress on particle fragmentation mechanisms, experimental methods, and engineering control measures, providing a reference for future studies in this field.
