摘　　要：东海大桥是我国第一座真正意义上的跨海大桥,东海大桥桥墩冲淤研究对类似海上风电、杭州湾大桥等跨海大桥冲刷防护等工程提供借鉴。多波束测深系统结合三维图像声呐在东海大桥水下地形测量的成熟运用为后期桥墩回填工程提供重要依据。冲淤变化直接影响桥墩桩基的桩基承载能力,桥墩基础局部冲刷深度是确定基础埋深和保证桥梁运行安全的重要参数,通过对多年东海大桥桥墩冲淤分析,为东海大桥整体冲淤评估提供可靠的数据依据。The Donghai Bridge is the first truly cross sea bridge in China.The research on the erosion and sedimentation of the piers of the Donghai Bridge provides reference for projects such as offshore wind power,Hangzhou Bay Bridge,and other cross sea bridge erosion protection.The mature application of multi beam sounding system combined with 3D image sonar in underwater terrain measurement of Donghai Bridge provides important basis for later bridge pier backfilling engineering.The changes in erosion and sedimentation directly affect the bearing capacity of the pile foundation of the bridge pier.The local erosion depth of the bridge pier foundation is an important parameter to determine the buried depth of the foundation and ensure the safe operation of the bridge.Through the analysis of erosion and sedimentation of the Donghai Bridge piers for many years,reliable data basis is provided for the overall evaluation of erosion and sedimentation of the Donghai Bridge.
