借助MATLAB数值分析软件,基于BP算法的误差逆传播网络,建立了巷道锚杆支护参数与锚杆轴力之间的映射关系。经过构建的神经网络平台的拟合可以较准确地得到支护锚杆的轴力,可用于对锚杆轴向受力状态的识别和巷道支护状况的评价,在巷道围岩稳定性和锚杆支护效果的监测中有一定的参考价值。 With MATLAB numerical analysis software, based on BP inverse error propagating network, the mapping relationship between bolt supporting parameters and bolt axial force is established. After fitting the neural network platform, the axial force of the supporting anchor can be obtained accurately, which can be used to identify the axial stress state of the anchor and evaluate the condition of roadway support. In the stability of the surrounding rock and anchor There is a certain reference value in the monitoring of rod support effect.
