PROBLEM TO BE SOLVED: To provide a bridge abutment settlement prevention structure of a bridge capable of effectively preventing the settlement of the bridge abutment by the cooperation of sheet piles supporting the bridge abutment and pressure receiving blades fitted to the bridge abuttment, providing a proper strength for supporting the bridge beam, reducing the size of the structures of the bridge abutment and the sheet piles, and reducing construction cost.;SOLUTION: This structure is formed so that the construction height of the bridge abutment 13 is set to such a height that the lower end of the bridge abutment13 does not reach a river floor 16, comprises the pressure receiving blades 25 formed integrally with the bridge abutment 13 which is extended from the side of the riverbank 12 of the bridge abutment 13 and buried in the ground 24 of the riverbank 12, and is formed so that the pressure receiving blades 25 are disposed at a height enabling to be buried in the ground 24 on the upper side of the river floor 16. A large number of sheet piles 26 are driven in the riverbank 12 in the form of joint in the lateral direction of the bridge, the upper ends of the sheet piles 26 are buried integrally in the bridge abutment 13, and a road pavement 27 is terminated on the riverbank 12 side on the upper side of the pressure receiving blades 25.;COPYRIGHT: (C)2005,JPO&NCIPI
