针对普通锚索在支护结束后留下大量地下垃圾,为城市地下空间的开发造成了阻碍的问题,将普通锚索与可回收锚索在作用机理、施工工艺、安全性以及经济型方面进行了详细深入的对比分析。分析结果表明,可回收锚索虽然增加了锚索回收工序及相应的施工设备,但规模化使用以及从长远角度考虑,施工成本有明显的降低。分析结果对可回收锚索的推广提供了一定的理论依据。 Aiming at the problem that ordinary anchor cable left a large amount of underground rubbish after the end of supporting, which hindered the development of underground space in the city, the ordinary anchor cable and the recoverable anchor cable were made in terms of mechanism of action, construction technique, safety and economy A detailed comparative analysis. The analysis results show that although the reusable anchor cable adds the anchor cable recovery process and the corresponding construction equipment, the construction cost is significantly reduced due to the large-scale use and long-term consideration. The analysis results provide some theoretical basis for the promotion of recyclable cable.
