Construction and Application of Bridge Pile Foundation Damage Assessment Model Combined with AHP and BN
In order to better evaluate the degree of damage to the bridge pile foundation in the Longhui Expressway section,achieve the safety and stability of the bridge,and achieve the purpose of safety management and timely maintenance of the bridge pile foundation.On the basis of surveying the damage of bridge pile foundations,this study combines the Analytic Hierarchy Process and Batch Normal-ization to establish an evaluation model for evaluating the damage of bridge pile foundations.The research results indicate that after the water level exceeds 4 m,the damage coefficient of the bridge pile foundation increases with the increase of water level,and when the water level is 7 m,the damage coefficient of the bridge pile foundation is 1.295.In addition,the damage coefficient of bridge pile foun-dation also increases with the increase of permeability,and the damage coefficient of bridge pile foundation under the permeability of 3.0% has increased by 0.11 compared to the permeability of 0.5%.
