高陡光滑岩质边坡绿化防护技术

Research on Greening Protection Technology for Smooth and Steep Rocky Slopes of High Rift Valley

由深路堑土石方开挖而形成的高陡光滑岩质边坡往往具有很大安全隐患和环境影响,需要采用有效的绿化防护技术以增强其稳定性和发挥生态功能。结合某高速公路扩建工程施工,从土工材料与植物生态条的结合、植物品种的选择与组合、以及土基加固等方面,探讨了适用于陡峭且光滑岩质边坡的绿化防护关键技术,包括TBS(turf base seeding)植草(灌)防护和喷播养护策略,增加客土厚度和采用双层TBS镀锌网片加固等。实践表明,上述措施能显著提升植被的绿化成活率和边坡的稳定性。研究结果可为类似地质环境下的绿化防护工程的设计与施工提供有价值的参考。

The high,steep,and smooth rocky slopes formed by the excavation of earth and rock from deep cuttings often pose significant safety hazards and environmental impacts,necessitating the use of effective greening protection techniques to enhance their stability and ecological functions.In the context of a highway expansion project,this paper explores key greening protection technologies suitable for steep and smooth rocky slopes.It focuses on the integration of geotechnical materials with plant ecological strips,the selection and combination of plant species,and soil reinforcement.Key techniques are introduced,including TBS(turf base seeding)grass(shrub)protection,hydroseeding maintenance strategies,increasing the thickness of the soil layer,and implementing double-layer galvanized TBS mesh reinforcement.Practice has shown that these measures can significantly improve the survival rate of vegetation and stability of the slopes.The research results provide valuable references for the design and construction of greening protection projects in similar geological environments.
