BP神经网络在区域滑坡危险性预测中的应用

由于区域滑坡危险性评价复杂性,在已知量和所求量之间往往存在着一种很强的非线性关系,而BP神经网络具备高度的非线性映射能力,因此采用BP神经网络来分析区域滑坡的危险性,可以取得良好的效果。本文结合具体区域滑坡危险性评价,使用Matlab神经网络工具箱中的相关函数建立具体BP神经网络,检验和预测区域滑坡的危险性。

APPLICATION BP ARTIFICIAL NEURAL NETWORK IN HAZARD PREDICT OF LANDSLIDE

Because of complexity of the regional landslide hazard assessment, the relation between known variants and unknown ones is very strong nonlinear. The BP neural network has high non-linear mapping capacity, and a good result can be obtained with BP neural network to analyze the regional landslide hazard. The paper creates BP neural network by use of Matlab neural network toolbox,combining regional landslide hazard assessment, to examine and predict hazard of regional landslide.
