摘要
通过分析锚杆的锈蚀作用机理 ,了解锚杆锈蚀对锚喷支护安全性的影响。分析结果说明 ,以砂浆锚杆为主体的锚喷支护安全能满足永久支护的要求 ,且锚杆支护与喷射混凝土支护作用是相辅相成的 。
By analysis of the principle of rockbolt rusting, the paper describes the security influence of rust of rockbolt on bolt spray supporting. Analysis results have shown that bolt spray supporting, in which mortar rockbolt is main supporting, can be satisfied fully by permanent supporting, and that rockbolt and shotcrete supplement each other while the improper constructing can bring severe influence to the permanence of boltspray supporting.
