摘　　要：在城市高架桥梁拼宽改建实施过程中,需对既有桥梁的全过程影响进行分析和评估。研究以上海市济阳路快速化改建工程为实例,提出一种新型拼接构造方案。通过相关试验,研究桥梁拼宽受力性能,在工程中进行实际应用,取得良好的效果。同时,对工程中桥梁拼宽的全过程影响进行评估,根据结果,提出全过程施工监测要求,制定监测方案,为今后类似工程提供参考和借鉴。During the implementation of widening & reconstruction of urban viaducts, it is necessary to analyze & evaluate the impact of existing bridges in the whole process. Taking the rapid reconstruction project of Jiyang Road in Shanghai as an example, a new splicing structure scheme is proposed. Through relevant tests, the mechanical performance of the structure is studied & applied in engineering;and good results are finally achieved. At the same time, the impact of the whole process of bridge widening in the project is evaluated, and according to the results, the requirements for the whole process of construction monitoring are proposed, and the monitoring scheme is formulated, which can provide reference for similar projects in the future.
