| 摘 要： | 主动防护网以其轻便美观等优点而被越来越多地应用于边坡落石防护,现阶段针对某一具体的边坡防护工程,其防护体系的设计多根据设计者的经验确定。主动防护网主要分为起围护作用的防护网和起加固作用的防护网,针对起加固作用的防护网进行了研究。根据防护网的实际工作状况,提出了防护网抗顶破力计算模型,理论分析了单根网格绳对球体落石的作用及主动防护网中钢丝绳网对球体落石的作用,推导了单根网格绳及主动防护网中钢丝绳网抗顶破力的计算公式,为起加固作用的防护网设计提供一定的参考价值。

| Abstract: | The cable nets rockfall protection systems has been widely used in slope protection against geological hazards.However,the design of this systems is mainly based on the experience of engineers.The systems can be divided into to two types,one is used when it is necessary to apply stabilization pressure over an unstable slope to avoid a soil or rock movement downhill,and the other is used,where the nets are not anchored to the slope,just on top,letting the debris fall into ditch,this article is presented here to study the first one.The calculated model is established based on the working conditionsof cable nets protection systems and the formulafor thesingle grid of the cable nets and the cable nets whichisto restraint the sphere-rockfall has been deduced,the results can be used to designthe active protection systems. |
