锚喷结构边坡表面绿化的新方法

NEW METHOD FOR SURFACE VEGETALIZATION OF SLOPES REINFORCED WITH ANCHORING BAR AND SHOTCRETE STRUCTURE

对于工程建设遗留下来的裸露边坡来说,锚喷结构是维持其长期稳定的高效加固措施之一。然而,在应用锚喷结构进行边坡加固的同时却有可能引起原有植被的破坏或与周边环境不协调等环保问题。现有的边坡绿化方法一般不适合于坡度大于60°的边坡,而利用锚喷结构进行加固的边坡却往往很陡。为此,提出锚喷结构边坡表面绿化的一种新方法。在该方法中,供植物生长的空间(包括绿化槽、绿化盆等)与锚喷结构是相互分离的,但在以下两方面又有所联系:第一,借助于锚杆和喷射混凝土来固定栽种植物所需的设施;第二,通过布置在锚喷结构上的排水孔为植物供水。对于这一相互分离的绿化方法,既保证足够的植物生长空间、水分和营养,又可避免植物根系及分泌物对锚喷结构的潜在损害。

For bare slopes caused by engineering construction,it is one of effective reinforcement methods for maintaining long-term stability of the slopes to utilize anchor and shotcrete structures.However,applications of the reinforcement method will lead to some negative problems for environmental protection,i.e.destroying original vegetations,not being harmonized with surroundings,and so on.Most slope greening methods are not suitable for slopes with slope angles larger than 60°,but the slopes reinforced with anchoring bar and shotcrete structures can usually be adopted for slope with a larger slope angle.For this reason,a new method for surface vegetalization of slopes reinforced with anchor and shotcrete is developed.In this method,spaces for plant growth are separated from the anchoring bar and shotcrete structures,but they have some mutual relations in following two points：firstly,establishments for plant growth can be fixed by using anchoring bars and shotcrete;and secondly,water for plant growth can be partly supplied by drainage holes arranged in anchoring bar and shotcrete structures.In the view,utilizing this method will not only ensure enough spaces for plant growth,but avoid potential damages of plants to the anchoring bar and shotcrete structures.
