摘　　要：首先,介绍了预应力混凝土曲线梁桥在施工和运营过程中经常出现的典型病害现象,并认为设计不当是产生病害的主因。然后,通过深入调研和文献查阅,分析了引起预应力混凝土曲线梁桥设计不当的原因。最后,基于多年的曲线梁桥设计实践经验,针对预应力混凝土曲线梁桥介绍了目前比较有建设性的设计意见和设计对策。First,the typical diseases that often occurred in concrete curved bridges are given,and thoughtle-ss in design of a pre-stressed concrete curved bridge is regarded as the cause of the typical diseases.Then,through investigation and data collection the reasons leading to improper design of pre-stressed concrete curved bridges are analyzed.Finally,based on many years of practice experience of the curved bridge design some constructive opinions and countermeasures for the pre-stressed concrete curved are offered.
