结合前人的研究成果，对神经网络理论中的BP算法进行综合改进，并将其运用于岩质边坡稳定性评判，建立了评判模型。结果表明改进的BP网络性能良好，所建立的模型预测精度较高，有一定的使用价值。
Combined with the research results of predecessors, the BP algorithm in neural network theory is improved synthetically and applied to the stability evaluation of rock slope, and the evaluation model is established. The results show that the improved BP network has good performance, and the established model has higher prediction accuracy and a certain value of use.
