摘要
结合旧桥加固实例,对以往预应力混凝土连续箱梁桥在实际建造和使用过程中出现的问题进行了分析,提出了相应的加固措施,并对加固效果进行了评定,结果表明:梁体受力情况得到明显改善,达到了预期的加固设计目标。
Combining with the reinforcement example of old bridge,this paper analyzed the problems of pre-stressed concrete continuous beam bridge in actual construction and use process,put forward corresponding reinforcement measures,and evaluated the reinforcement effect,the results showed that,the stress conditions of beam improved obviously,achieved expected reinforcement design target.
