摘要
采用数值方法,模拟全粘结岩石锚杆的拉拔试验,求得不同条件下的岩石锚杆水平刚度系数,最后经曲线拟合和参数分析,推导出岩石锚杆水平刚度系数的计算公式。与有关试验结果的对比表明,公式计算结果与实际比较接近。
The horizontal stiffness coefficient values of rock anchor under different conditions are obtained through using numerical method to simulate the pullout test of the fully-grouted rock anchor. Based on curve fitting between the calculation parameters and results and parameters analysis, a formula is derived for the coefficient calculation.Comparison with some related tests shows that the calculation results of the formula approaches to the real situation.
