Study On The Influence Of Tidal Traffic On The Safety Of Urban Single Column Piers

Because the structure of the Single Column Bridge has particularity and complexity, the research of the single column bridge collapse in the security and stability was quite scarce. So it is necessary to analyze the actual single column bridge and the static effect and dynamic effect on the bridge. The study focused on the following aspects:This article will firstly analyze different combinations of tidal effect of transport on the static and dynamic effects of urban single pier of the bridge structure By finite element software ABAQUS, only to find out facts on affecting its safety. In this paper, the conclusion is as follows:(1)Consider the traffic tidal dynamic effects at idle,its data is basically the same as the effect with static tide of traffic laws. And the power load effects consisting entirely of non-conventional triaxial Truck traffic is the biggest for the other vehicle dynamic load effects.(2)The rules of the tidal traffic under consideration of dynamic effects of engine idling and without considering the effect of static idling are: The dynamic load effects triaxial dynamic load effects of heavy vehicles>The two-axis dynamic loading effect of heavy vehicles>The dynamic load effect of the large buses> The dynamic load effect of the minibuses.(3)The tidal traffic consider dynamic effects are larger than the effect of static idle.So when we consider the tidal effects on traffic on the bridge pier alone time, not only to consider the tide of traffic on the single bridge pier Effect of static load, but also taking into account the impact of dynamic load effects idling of Single- pier under the bridge.
