| 摘 要： | 以某桥梁因渣土堆积造成桥墩偏位超限为例,对桥墩偏位超限所在桥跨结构进行外观检测、实体检测和安全评估计算,结果表明:左幅50#墩~52#墩、右幅49#墩~51#墩,桩基及墩身损伤严重,承载能力不满足规范及设计要求,存在重大安全隐患,须加固处治。

| Abstract: | Taking a bridge on a expressway in Chongqing with bridge pier deflection because of slag accumulation as an example,the appearance inspection,entity inspection and safety assessment calculation of the bridge span structure where the bridge pier deflection exceeds the limit are carried out.The results show that the left 50^#~52^#,the right 49^#~51^#,the pile foundation and pier body are seriously damaged,the bearing capacity does not meet the specifications and design requirements,and there are major safety risks. |
