锚杆+格梁支护是目前边坡防护中最常用的支护形式之一。格梁斜向设置于坡面,施工难度大,造价高,工期长,施工质量难以保证;在水流长期冲刷及渗透作用下,容易造成格梁底岩土体流失,使格梁与坡面岩土体脱空,从而导致部分支护结构失效。该文提出一种新型的无格梁的边坡支护结构体系,边坡支护仅由锚杆完成,坡面可同时进行植物防护或柔性防护,也可以在锚杆之间设置土钉,以加强坡面岩土体的局部稳定。该支护结构克服格梁存在的问题,施工简单,降低工程造价,坡面美观,有利于锚筋永久性防腐。该新型支护结构体系可应用于实际工程,具有良好的应用前景。
Bolting and girder support is one of the most commonly used forms of support in slope protection. Under the long-term scouring and infiltration of water flow, it is easy to cause the loss of rock and soil mass at the bottom of the girder, so that the grid girder and the slope rock Soil is empty, resulting in failure of some support structures. In this paper, a new type of lattice girder-free slope supporting structure system is proposed. The supporting of the slope is only accomplished by the anchor rod. The slope can carry out plant protection or flexible protection at the same time. Soil nailing can also be set between the anchors, In order to strengthen the local stability of rock and soil slope. The supporting structure overcomes the existing problems of the grid beam, has simple construction, low construction cost, beautiful slope surface, and is favorable for the permanent preservation of the anchorage rib. The new type of supporting structure system can be applied to practical engineering and has good application prospect.
