高等级公路路基边坡稳定性病害分析及防治

Control measures and disease analysis of the high-grade highway roadbed slope stability

高等级公路路基边坡防护是防止路基病害、保证路基稳定、改善道路环境、保护生态平衡的重要措施,也直接关系到路基的外观,影响路线景观和环境协调。但是,目前多数高等级公路建设由于缺乏对防护工程的系统研究,许多工程只能借用低等级公路的防护技术,给高等级公路工程建设带来了隐患,造成了巨大的经济损失和不良的社会影响。本文讨论了高等级公路路基边坡稳定性破坏形式、产生病害的主要因素以及防治对策,确保高等级公路安全使用。

It is an important measure that roadbed slope of the high-grade highway was protectived to prevent subgrade disease, ensure roadbed stabilization, improve road environmental landscape and protect ecological balance, and it directly concerns that of external appearance of the roadbed and route landscapes etc. However, systematic study of the subgrade protection project in the current lots construction of high-grade highway were ignored, and many project adopt the protection technology of the low-grade highway to hidden danger for project construction of the high-grade highway, which lead to the enormous economic loss and exert a bad publicity. Failure modes and main disease factors of the high-grade highway roadbed slope stability were discussed, and control measures were presented to ensure safe application of the high-grade highway.
