中国路基工程学术研究综述·2021

作为路面的基础，稳定、坚实、耐久的路基是确保路面质量的关键，而中国一直存在着“重路面、轻路基”的现象，使得路基病害导致的路面问题屡禁不止。近年来，已有越来越多的学者注意到了路面病害与路基质量的关联性，从而促进了路基工程相关的新理论、新方法、新技术等不断涌现。该综述以近几年路基工程相关的国家科技奖的技术创新内容、科技部及国家自然科学基金项目、优秀中文权威期刊的论文、Web of Science中的高水平论文的关键词为依据，系统分析了国内外路基工程五大领域的研究现状及未来的发展方向。具体涵盖了：地基处理新技术、路堤填料工程特性、多场耦合作用下路堤结构性能演变规律、路堑边坡的稳定性、路基支挡与防护等。可为路基工程领域的研究人员与技术人员提供参考和借鉴。

Review on China's Subgrade Engineering Research·2021

As the foundation of the pavement structure, a stable, strong and durable subgrade plays a key role in the quality protection of pavement. However, the phenomenon of paying attention to road surface but neglecting subgrade has existed in China for a long time, and makes it very common that the subgrade diseases lead to the destruction of pavement structure. Based on the subgrade engineering in recent years related the technical innovation contents of the China's National Science and Technology Award, the projects of the Ministry of Science and Technology (MOST) and the National Natural Science Foundation of China (NSFC), the excellent Chinese authoritative journals, and the highly cited papers in Web of Science (WoS), this review paper systematically analyzes the research status and future development direction of 5 major fields of pavement engineering in China and abroad. This content includes advanced foundation treatment technology, embankment filling engineering properties, embankment structural performance evolution under multi-field coupling action, cutting slope stability analysis, subgrade retaining and protection. Overall, this review paper is able to provide references and insights for researchers and engineers in the field of subgrade engineering.
