Abstract: Gravity abutment widely uses for substructure part of the bridge structure. For many reasons, there are many damages take place in the parts of abutment. The objective of this study is to evaluate the strengthening effects on the performance of highly structure of Gravity abutment. The results of damage inspection show that these damages are very serious in the direction of height and width of the abutment structure. Therefore, there is need to strengthen the abutment structure to improve the carrying capacity. There are two experimental models. The first model uses one ring of carbon fiber sheet and the second uses two rings of carbon fiber sheet .The results of experimental show that there are good effects when using carbon fiber sheet strengthening method.

The objective of this study is to evaluate the strengthening effects on the performance of highly structure of Gravity abutment. ANSYS ver.10 software is used in the theoretical analysis of capacity of abutment structure .There are two experimental models. The first model uses one ring of carbon fiber sheet and the second uses two rings of carbon fiber sheet .The results of theoretical analysis show that there are good effects when using carbon fiber sheet strengthening method.

Abstract: Bridge is the most modern transportation systems more see the composition of the form, the construction of bridge engineering helps to relieve the pressure on the ground transportation, realize the efficiency of regional traffic comprehensive improvement. Domestic vehicle number has doubled in recent years, frequent traffic activities make bridge is facing serious gravity load, and a variety of diseases, threatening the safety of the bridge deck vehicle. Construction units in construction phase, should pay attention to the maintenance of bridge structure disease treatment, put forward a practical and reliable solutions. Half through bridge were examined in this paper, based on an engineering example, analyzed the common deterioration problems of concrete filled steel tube arch bridge, the corresponding protective measures are put forward.

Abstract: It is major, simple structure and wide scope of use on Gravity abutment of plain concrete, But most of the wall of abutment appears irregular cracks, affect the economy and durability of the abutment and bridge seriously. The paper is based on a bridge of Jiang Xi Rui Xun high-speed engineering, analysis the crack mechanism of abutment by using large-scale finite element software ANSYS to establish reinforcement simulation model of top and bottom ring beam. The stress and vertical deflection of the abutment are meet the requirements, it is meaningful for gravity abutment of plain concrete Strengthening in the future.
