摘要
针对高速公路上的部分预应力组合箱梁病害进行了加固实践。从荷载标准确定计算依据,分析病害产生原因,从而制订稳妥有效的加固方案,并成功地进行了实施,供同类工程参考。
According to the diseases of partially prestressed concrete composite box girder in highway,the practicc of reinforcement is carried out.The computation basis is determined from the load standard.And reasons of the diseases are analysed.Then the safe and effective scheme is formulated and implemented sucessfully,which can be referenced by the similar engineerings.
