摘要
杭州湾跨海大桥全长36 km,设有南、北两座斜拉桥,海上引桥上部结构为30m、50m、70m和80m箱梁,下部基础为钢管桩和灌注桩,结构复杂,杭州湾海域环境恶劣,腐蚀强,潮差大、潮流急、冲刷深,杭州湾特定的气象、水文、地质特点,增加了养护工作的难度。在建设过程中探索并解决了一些技术难题,在运营阶段继续研究、探索海湾环境桥梁养护的规律。现就杭州湾跨海大桥养护管理工作予以阐述和分析。
The total length of Hangzhou Bay Bridge is 36km, composed of two cable - stayed bridges located on the northern and southern sides, respectively, and the approaching bridges which are mainly composed of the box girder with the spans of 30m, 50m, 70m and 80m. The substructure of Hangzhou Bay Bridge is steel pile and east - in - place pile. The complexity of the structure, the severe ocean environment, strong erosion, large change in tide and fast speed of the tide, the deep scour, as well as the features of climate, hydraulics and geology, increase the difficulty of the mainte- nance of Hangzhou Bay Bridge. During the construction of the bridge, some claallenging technique problems have been solved, but some are still need to be studied during the operation stage, in order to master the rules for optimum mainte- nance of the bridge under the bay environment. In this paper, the management work of Hangzhou Bay ocean- crossing bridge is elaborately introduced and analyzed.
