摘　　要：随着高速公路的快速发展,公路建设中山地开挖形成大量裸露的边坡,既破坏公路景观,又造成水土流失。客土喷播能在普通条件下无法绿化或绿化效果较差的岩石边坡上实现草灌结合,立体绿化,恢复自然植被。宁常高速公路南京标段岩石边坡坡度60°-70°,平均高度20 m,板状石质,质地坚硬。结合该标段施工实例,论述了岩石边坡客土喷播所需材料和设备、施工流程和技术要点、验收要点和标准。实践证明,客土喷播绿化速度快、植被覆盖率高,是高速公路岩石边坡绿化的一种新方法。Along with the fast development of express highway,a large area of slope became bare and it results in water and soil erosion.Spray seeding could achieve three-dimensional greening with shrub and grass.Taking Nanjing Changzhou Express Highway（Section in Nanjing City） as the example（where the gradient of rocky slope was 60 to 700 degrees,the average height was 20 m and the ground substance was very hard）,the materials,equipments,key techniques and construction standards were summarized.It could be concluded in this example that spray seeding was an efficient approach to rapidly establish vegetation cover on rocky slope.
