Many cast-in-site bore pile have broken pile because of collapsing in wall of holl. Based on the principle of mechanics, a new combination approach was proposed for dealing with the broken pile. The approach is displacing the soil in the pile by cement paste and increasing the height and the steal ratio of the top beam which is on the defect pile. Using the finite element software, we have set up the analysis model of the approach, which helps to demonstrate the rationality of this method. This method can be referenced by the reinforcement and maintenance of the bridges.
