The Influence of Structural and Materials on Bridge Stability and Stabilization Measures

Abstract

Bridges are now not only an auxiliary tool for travel, but it is also an important way to measure a country's comprehensive strength. Because the stability of a bridge structure is affected by a variety of professional knowledge and various aids which made by advanced technology. So whether the bridge is stable and how to be more stable are the focus of discussion. This paper mainly analyzes and summarizes the stability of the bridge from the perspective of influencing factors and structural principles, and puts forward some measures which could improve stability accordingly. It includes the most common natural factors: earthquake and flood, which need to be considered from different perspectives due to their different failure principles and structures. As for the bridge structure itself, its upper and lower structures have cracks or lack bearing capacity, resulting in uneven settlement of the foundation. The sliding and tilting of the foundation and the local voids in the foundation are all factors that endanger the stability of the bridge. As for the effects of cracks, freeze-thaw denudation, scouring and grinding, cavitation erosion, water erosion, weathering and denudation of materials, they should be considered as important factors. Moreover, the improvement of the existing technology, such as strengthening the anti-corrosion layer, waterproof layer and protective layer, are also important.
