| Abstract: | Through practical example and combined with the basic principle of finite element method,and utilizing the analog calculation of large finite element,Ansys,it is analyzed that the major cause to cracks on U-type bridge abutment is earth pressure,and the suggestion to use CFRP on reinforcement of cracks on abutment is promoted. |
