摘要
随着高陡边坡被动网、主动网等柔性防护方式的运用,其功能缺陷凸显出来,结合范家坪高边坡多道被动网在落石冲击下被破坏损毁现象,分析其落石运动轨迹及冲击能量,结果显示原被动网设计不合理,提出了张口式帘式网防护网设计,并运用数值模拟方式得出其防护能够满足需求,根据数值模拟分析结果给出了范家坪具体的防护设计方式。
With the application of flexible protection such as passive net and active net for high-steep slope,their functional defects become prominent.Combined with the phenomenon that the passive net of the high slope of Fanjiaping is damaged by rockfall impact,the trajectory of the rockfall movement and the impact energy are analyzed.The results show that the the original design of passive net is unreasonable.This paper puts forward the design of curtain mesh protective net,and the result of the numerical simulation show that curtain mesh protective protection can meet the demand,according to the numerical simulation analysis results,it gives the specific protective design method of Fanjiaping.
