摘要
通过对预应力锚杆加固软岩巷道时加固参数预应力变化的模拟得到其对锚固效果的影响曲线,并根据曲线确定了影响参数和径向位移之间的函数式,进而对变形最小时的影响参数给出分析及评价,从而为巷道加固提供理论参数。
Through the analysis of the parameters advanced reinforcement of the pre-stressed bolt reinforcement of soft rock roadway, it＇s anchor on the effect of curve is drawn, the functional between the parameters and the radial displacement were decided according to the curve, and then the parameters of minimum deformation were analyzed and appraised, which provided theory parameters for the reinforcement of roadway.
