本书针对跨海特大型桥梁面临的深水、强风、巨浪、急流等复杂恶劣环境挑战,面向跨海桥梁建设需要,对桥梁风?浪?流耦合作用的现场观测、耦合特性、模型试验、数值模拟、振动理论及控制措施等关键技术进行了详细论述。具体包括:桥梁风?浪?流耦合场现场观测方法及耦合特性分析、桥梁风?浪?流耦合场数值模拟及设计参数取值方法、桥梁风?浪?流耦合作用弹性模型试验模拟方法及动态响应特性、桥梁风?浪?流耦合作用数值水槽模拟方法、桥梁风?浪?流耦合作用的随机振动理论及分析方法、车?桥?风?浪?流耦合作用的随机振动理论及分析方法、大型深水预制基础沉放过程数值模拟及控制措施等。相关创新成果为港珠澳大桥、深中通道工程等特大型跨海桥梁工程建设提供了重要技术支撑和储备。本书可供从事跨海桥梁设计、科研、教学等工作的技术人员参考使用。AbstractFor construction demand and harsh environmental challenges such as deep water, strong winds, huge waves and rapidcurrent faced by Super?large Cross?sea bridge, this monograph discusses the key technologies such as fieldobservation,coupling characteristics,model test,numerical simulation,vibration theory and control measures of bridgewind?wave?current coupling action. The main contents include on?site observation method,coupling characteristicanalysis,numerical simulation of wind?wave?current coupling field and design parameter determination method. Themain contents also include elastic model test simulation method of bridge wind?wave?current coupling action anddynamic response characteristics,bridge wind?wave?current coupling numerical water tank simulation method,bridgewind?wave?current coupling random vibration theory and analysis method,vehicle?bridge?wind?wave?current couplingvibration theory and analysis method, numerical simulation and control measures for large?scale deep waterprefabricated foundation in sinking process,etc. Relevant innovations have provided important technical support andreserves for the construction of Super?large Cross?sea bridge projects such as Hong Kong?Zhuhai?Macao Bridge,Shenzhong Channel Project.The monograph can be used by technicians who are engaged in Super?large Cross?sea bridge design, research,teaching,etc.
