摘要
桥墩产生裂缝的原因很多,结合对某大桥桥墩裂缝的加固处理,分析了其产生的原因,并结合工程实际,提出了粘贴钢板法、碳纤维包裹法、体外预应力法等几种加固方法,并对几种方法进行了比选,最后重点介绍了采用体外预应力的加固方法及其施工过程。
There might be various causes leading to the cracks in bridge piers. With reference to the strengthening of the piers of a bridge, the causes of the cracks in the piers are analyzed. Several methods, such as binding of steel plates, wrapping with carbon fibre reinforced polymer (CFRP) texture and using of external prestressing are proposed and compared. Finally, the strengthening method and construction process with the extemal prestressing are presented in details.
