随着国民经济建设不段发展,公路交通事业日新月异,高速公路日益增多,人们出行带来极大便利。但由于道路边坡失稳影响行车安全,甚至掩埋道路,中断交通,造成不可估计的经济损失事件时有发生。所以加强道路边坡防护至关重要,根据地质条件、水文地质条件、气候条件、地形地藐等多种因素影响,所采取的边坡防护相应措施也不同,根据湖南地形、气候条件、地质状况,路基边坡在春雨季影响较大,加强雨季对道路路基边坡防护,是确保高速公路良好行车安全一项重要措施。
With the non-development of the national economy, the road transport industry is changing with each passing day, the number of highways is increasing, and people travel greatly. However, due to the instability of road slopes affecting traffic safety, and even buried roads, traffic interruptions, resulting in unpredictable economic losses have occurred. Therefore, it is very important to strengthen the protection of roadside slope. According to the geological conditions, hydrogeological conditions, climatic conditions, topography and other factors, the corresponding measures for slope protection are also different. According to the topography, climatic conditions, geological conditions , The slope of subgrade is more influential in the spring rainy season. Strengthening the protection of roadbed slope during the rainy season is an important measure to ensure the good traffic safety of the expressway.
