摘　　要：针对市政桥梁在现有构筑物、城市规划、河涌防洪要求、建设时序等多条件受限问题,依托既有项目实例,从桥型确定、上下部结构选型等方面进行阐述,总结出优先选择既安全又满足各部门要求的桥梁方案;上部结构可结合景观要求对防洪要求进行微调;下部结构按实际需求选择避开或合建方案,并互相提资确定结构安全性等结论,为今后类似工程提供相关设计思路和经验。In view of the limited conditions of municipal bridges in existing structures,urban planning,river flood control requirements,construction sequence and other conditions,relying on the existing project examples,expounds the determination of bridge type and the selection of superstructure and substructure,and summarizes the priority selection of bridge schemes that are safe and meet the requirements of various departments.The upper structure can be fine-tuned for flood control requirements in combination with landscape requirements.The substructure chooses to avoid or jointly construct the scheme according to the actual needs,and mutually proposes to determine the structural safety and other conclusions,providing relevant design ideas and experience for similar projects in the future.
