摘　　要：在公路工程中,广泛应用的大跨度连续梁和连续刚构预应力混凝土梁式桥运营后出现诸多病害。结合多年设计经验,从结构总体、预应力构造、施工要求等方面进行精细化设计,并提出了延长桥梁耐久性的优化建议。In highway engineering, the long spans pre-stressed eoncretebeambridgeswithcontinuousbeamorcontinuousrigidframe have been widely built The author gets detailed prospecting on architectural formmanydiseases, the refmed designwas appliedwith overall structure design, pre-stressed construction and structural calculation. The structural design optimization was advised on improving the concrete structure durability.
