Research On The Damage Assessment Of The Steel Reinforced Concrete Foundation

With the continuous development of Chinese economic construction, the speed of road construction is constantly improving, including bridge construction. The bridges models are more novel and the span is also growing. However, the accidents happen at the same time, and these serious accidents caused by bridges’ collapsing bring huge economic losses and adverse social impact. The painful accidents above remind us of attaching importance to the quality of the project, and propose the topic: whether the foundation can continue to be used in the repair parts or not.The damage assessment of ramp foundation of interchange overpass is performed in this paper. The main content deals with the quality detection of concrete material of the foundation; the assessment of the pile integrity, strength and deformation of the foundation of bridge; the assessment of the smoothness and quality of pile cap of bridge pier; the integrity, strength and deformation of the bridge pile; the analysis of influence of the horizontal force on pile foundation of overpass. The results show that the concrete strength can meet the requirement, the pile integrity can accord with the code standard, and the smoothness of pile cap of bridge pier can meet the requirement. The finite element results indicate that the of influence of the horizontal force on the foundation of the bridge is very small. The maximum bending moment of the pile is small and the horizontal deformation of the pile foundation caused by the horizontal force is elastic and not harmful to the pile. So the pile could safely be used.
