According to the basic principles of neural networks and in combination with 35 examples of actual landslide projects, this paper establishes RBF and BP neural network models respectively. The comparative results of the two models show that RBF neural network model has higher accuracy and fewer errors and is more suitable for the stability evaluation of landslide. Therefore, this model is used to calculate the stability coefficients of Yellow Caoba ancient landslide and predict the stability of the landslide.

根据神经网络的基本原理，结合35个实际滑坡工程实例，分别采用RBF神经网络和BP神经网络建立滑坡稳定性评价模型，利用MATLAB编程求解，并对比了两种模型的计算结果，表明采用RBF网络模型计算出的结果精度高、误差小，更适合于对滑坡的稳定性评价；同时，运用RBF网络模型计算了黄草坝古滑坡的稳定性系数，对其稳定性进行了预测，以验证该方法的有效性。
