分析了现行锚杆尾部的破断机制 ,研制了一种新型金属粗尾锚杆 ,阐明了新型金属粗尾锚杆的防破断机理。通过分析 ,得出金属粗尾锚杆较其它锚杆不易发生断裂
The breaking mechanism of the existing anchor tail is analyzed and a new type of metal thick tail anchor rod is developed. The breaking mechanism of the new type of metal tail anchor rod is illustrated. Through analysis, it is concluded that the metal thick-tail anchor is less prone to fracture than the other anchor
