在高速公路建设中,挖方路段形成裸露的路堑坡面,既破坏了植被,有损生态平衡,又极易受风雨等的侵蚀,导致水土流失,危及公路的安全。过去常采用浆砌条石或水泥喷浆等构造物进行护坡处理,随着人们环保及审美意识的提高,需对裸露的坡面进行绿化处理,以防止坡面的侵蚀和风化,恢复自然植被,在绿化的同时起到美化的作用,以求达到“人在车中坐,车在画中行”的意境。现土质坡面绿化方法已在多条高速公路应用并取得很好的效果,但岩质坡面绿化效果不太理想。土壤和水分是植物生长的必要条件之一。对于岩质坡面,其硬度大、土壤少甚至无,植物生根、发育非常困难。因
In the expressway construction, the excavation of road sections forms bare road cutting slopes, which not only destroy the vegetation, impair the ecological balance, but also are extremely vulnerable to wind, rain and other erosion, resulting in soil erosion and endangering the safety of the road. In the past, masonry stone or cement grouting structures were used for slope protection treatment. With the improvement of people’s environmental protection and aesthetic awareness, it is necessary to green the exposed slope to prevent erosion and weathering on the slope surface and to restore natural vegetation , At the same time beautify the role of landscaping, in order to achieve “people sitting in the car, the car in the painting Bank ” mood. The method of afforestation on the soil surface nowadays has been applied on many expressways and achieved good results, but the greening effect of rocky slope is not very satisfactory. Soil and water are one of the necessary conditions for plant growth. For rock slope, its hardness, soil less or even, plant roots, development is very difficult. because
