摘　　要：锚杆锚固特性是决定围岩锚杆支护成败的关键,协调好锚杆参数可以实现安全、经济、高效的支护效果。不同的锚杆类型在不同条件下对围岩体的控制作用千差万别,为了进一步了解锚杆的锚固特性,采用理论分析和现场试验相结合的方法对影响岩石锚杆锚固特性的初锚力与锚固长度的关系进行研究。得到初锚力对围岩的横向挤压指标,获得了一种有效的工程应用下的快速计算锚固长度的计算模型公式,可以更好地指导实际工程中的岩巷锚杆支护问题。The bolt anchorage characteristics are the key to the success or failure of surrounding rock bolt support.Reasonable bolt parameters can achieve safe,economic and efficient support effect.The control effects of different bolt types on surrounding rock vary greatly under different conditions.In order to further understand the anchorage characteristics of bolt,the relationship between initial anchorage force and anchorage length affecting the anchorage characteristics of rock bolt is studied by combining theoretical analysis and field test.Through the research,the lateral compression index of the initial anchorage force on the surrounding rock is gained,and an effective calculation formula for quickly calculating the anchorage length under engineering application is obtained,which can better guide the bolt support of rock roadway in practical engineering.
