摘 要
山区高速公路建设过程中，高边坡稳定性问题直接影响工程安全与运营质量。传统边坡防护措施在提升稳定性的同时，常忽视生态环境的协调性与可持续性。本研究旨在综合地质条件、力学特性与生态要素，构建科学合理的高边坡稳定性评价体系，并提出兼顾安全性与生态效益的新型防护技术。基于多源数据融合分析方法，结合现场监测与数值模拟手段，对典型路段高边坡进行稳定性分区评价，并引入植被恢复指数评估生态修复效果。研究结果表明，所提出的评价模型具有较高的准确性与适用性，能够有效识别潜在失稳区域；同时，集成植物根系固土作用与柔性支护结构的复合生态防护技术，在提升边坡稳定性方面表现出良好性能，且显著改善了地表覆盖度与水土保持能力。本研究创新性地将生态功能量化纳入边坡稳定性分析框架，提出了适用于复杂山地环境的分级生态防护策略，为绿色公路建设提供了理论支持与技术路径。

ABSTRACT
During the construction of highways in mountainous areas, the stability of high slopes directly affects engineering safety and operational quality. Traditional slope protection measures often overlook the harmony and sustainability of the ecological environment while enhancing stability. This study aims to develop a scientifically sound and reasonable evaluation system for high slope stability by integrating geological conditions, mechanical properties, and ecological factors, and to propose new protective techniques that balance safety and ecological benefits. Using a multi-source data fusion analysis approach combined with field monitoring and numerical simulation, this research conducts stability zoning assessments on high slopes along typical road sections, and introduces a vegetation restoration index to evaluate the effectiveness of ecological restoration. Results indicate that the proposed evaluation model demonstrates high accuracy and applicability, effectively identifying potentially unstable areas. Furthermore, the integrated ecological protection technique, which combines the soil-stabilizing effects of plant roots with flexible support structures, exhibits excellent performance in enhancing slope stability while significantly improving surface coverage and soil and water conservation capacity. This study innovatively incorporates quantified ecological functions into the slope stability analysis fr amework, proposing graded ecological protection strategies suitable for complex mountainous environments, thereby providing theoretical support and technical pathways for green highway construction.
