The Influence Of Settlement On Bridge Base And The Control Of Crack

Bridge foundation belong to commonly rigid foundation, from rc rigid pile foundationand foundation to expand open caisson basis. Small and medium-sized Bridges generallyUSES the basic form is the concrete rigid expand foundation, bridge and super majorbridge is the foundation and the open caisson pile foundation. The engineering geologicalconditions and the upper bridge structure type selection.This paper with some specific engineering simply introduced the foundationsettlement of bridge structure effect, and established a base settlement of bridge structureaffect practical mechanics calculation model, to base settlement of the internal forceredistribution of the bridge structure and the correlation analysis.In the paper, the bridge, the settlement of foundation of each of the control method ofthe preliminary analysis and summarized, pile foundation and foundation of open caissonconstruction process of the testing method and the problems to be pay attention to in basicgeneralizations. And simple introduces bridge foundation settlement of testing method.Simple introduces the component of the bridge crack, to bridge crack types andreasons of, the common control measures and repair methods of cracks in the preliminarysummary. And combined with engineering practice of the influence of the bridge cracksimple summary, finally the uneven settlement of foundation caused by the cause of thebridge crack are discussed in this paper.
