:从建立强潮地区桥墩局部冲刷模型的重要性 发, 简要介绍了通过水槽试验所建立的杭 州湾跨海大桥局
部冲刷模型.强潮特性使得杭州湾跨海大桥桥墩局部冲刷的实际数据获取难度较大, 据此提 了基于海底声学探
测技术的数据获取方案,即利用多波束测深技术进行桥墩局部海床高程测量、利用多普勒声学测量技术进行潮流
测量等, 同时结合底质钻孔取样进行底质分析.在介绍了实测数据的处理方法后, 结合桥墩设计资料进行了模型参
数的计算及模型验证, 并根据桥墩实际情况对验证结果进行了相关分析, 最后肯定了本方案对于强潮地区进行桥
墩局部冲刷观测的适用性.

Abstract:Starting with the importance of setting up pier local scour model for the bridge in the strong tide region, the
pier local scour model of Hangzhou Bay sea-crossing bridge built on theflume experiments is introduced.The strong
tide in Hangzhou Bay estuary makes it very difficult to obtain the real
