边坡落石柔性防护系统易维修性试验研究

Experimental Study on Maintainability of Slope Rockfall Flexible Protection System

目前,国内已建成有2座试验平台开展边坡落石柔性防护系统足尺冲击试验研究,并制定了落石冲击试验方法与评价方法。为分析防护系统易修复性等级,做了2组足尺试验模型落石冲击对比试验,对2组试验模型的易维修性等级进行了评价。结果表明,减压环的布置方式与连接方式是柔性防护系统受冲击后易维修性的关键因素。

At present, two test platforms have been built in China to carry out full-scale impact test research on the slope rockfall barrier system, and the rockfall impact test method and evaluation method have been formulated. In order to analyze the grade evaluation of repairability, two sets of full-scale test models were tested for rockfall impact, and the repairability grades of the two sets of test models were evaluated. The results show that the arrangement and connection of the ring-break are the key factors for the easy maintenance of the rockfall barrier system, which can provide a reference for engineering applications.
