Research on operation behaviorevaluation of bridge anchorage based on AHP

The bridge anchorage is the important construction work unit, which whether its operating condition is normal or not will directly influence the normal operating of bridge. So, it is very important to judge the bridge anchorage operation behavior. The method of the analytical hierarchy process is introduced and the model for bridge anchorage safety has been developed by using AHP in this paper. On basis of it the bridge anchorage operation behavior is evaluated by using BP neural network and analyzing its application.
