摘要
旭龙水电站地处四川、云南、西藏三省交界地带,河谷两侧多为山体,植被缺乏,裂隙破碎带较多,安全风险高。传统的边坡防护设计主要着重于对钢性结构防护措施的设计,在设计上,主要采用可以确保边坡稳定的砌石防护和防护钢架网的形式。主动防护网的工作原理类似于喷锚、土钉墙等地表护坡,然而,由于其灵活的特性,一些集中载荷可以分布到周围地区,充分发挥整个系统的保护能力,即部分加载和整体作用,使系统能承受更大的载荷,降低单个锚栓的锚固力要求。绿色植物可以在它们的开放空间自由生长,通过包裹或覆盖在需要防护的斜坡、有崩塌可能的大山或者岩石等危险的地方,用来减缓坡面多岩石的山坡土壤的风化和危险岩石的掉落,将落石控制在一定范围内,防止因其掉落而破坏附近高速公路、汽车、建筑物,甚至砸伤行人等。
Xulong Hydropower Station is located at the border area of Sichuan,Yunnan and Tibet.The two sides of the valley are mostly mountains,lack of vegetation,and there are many cracks and fracture zones,so the safety risk is high.The traditional slope protection design mainly focuses on the design of the protective measures of the steel structure.In the design,it mainly adopts the form of the stone masonry protection and the protective steel frame net that can ensure the stability of the slope.Actively defend the net work principle is similar to spray anchor and soil nailing wall surface,such as slope protection,however,because of its flexible features,some of the concentrated load can be distributed to the surrounding area,give full play to the protection of the whole system,that is part of the load and the overall effect,make the system to accept a larger load,reduces anchoring force requirements for individual bolts.Green plants can grow in their freedom of open space,through the parcel or covered in need of protection slope,or the collapse of mountain hazards such as rock,used to slow down the slope of rocky slope soil weathering and dangerous rock falling,control the rock fall within a certain range,prevent the hit and damage near by highways,automobiles,buildings,and pedestrians.
