Abstract
In order to improve the bearing performance of bridge pile foundation,a bridge pile foundation model was established by MIDAS software to analyze the bearing performance and variation characteristics of reinforced concrete bridge pile foundation under the coupling action of erosion and material degradation.The results show that the pile settlement increases with the increase of load,and the more serious the ero-sion degree,the more obvious the pile settlement.With the increase of service life,the ultimate bearing capacity of pile foundation decreases rapidly at first(less than 20 years)and then tends to be flat(20～100 years).When the service life is more than 20 years,the difference of pile foundation settlement before and after concrete deterioration is more significant.关键词
