Study on the Construction Site Safety Assessment Based on PCA and BP Neural Network

摘要：

A new method based on the integration of PCA (Principal Component Analysis, PCA) and BP neural network is put forward for the construction site safety assessment. The dimensions of index system are reduced by PCA. Then, the data of the indexes reduced is input into BP neural network and finally the method is applying to 12 construction sites of Qingdao. Empirical study has shown that the method used in the construction site safety assessment is feasible and reliable.
