摘要
文中结合5．12汶川特大地震中公路、铁路路基边坡、防护及支挡工程的典型破坏形式和相关总结、探讨，对传统的路基支挡结构物在地震中的破坏情况及受力机理进行系统分析，并结合国内外在工程领域的应用实践成果，探索、改进和提出一些抗震性能优越、经济合理而又适宜高烈度地震区应用的新型结构与措施。
Combined with the typical destruction of highway and railway subgrade slopes, protecting and retaining structures in 5.12 Wenchuan Earthquake as well as the relevant conclusion and discussion, this paper makes systematic analysis on damages and stress mechanism of traditional subgrade retaining structure in earthquake. Together with the application practice in engineering field both at home and abroad, it presents some exploration and improvement on economical and reasonable new type structure and measures with excellent earthquake resistance for high intensity earthquake area.
