该文依托港珠澳大桥埋置式承台足尺模型工艺试验项目,采用理论计算分析与原位试验监测相结合的方法对埋置式承台与桩的波流作用动力响应进行研究。理论计算分析采用流体力学计算软件Flunt、Sesam与通用有限元计算软件Ansys相结合的方法,对波流作用下的承台与桩的动力响应进行分析,并结合原位试验与动态监测,揭示了承台与桩在波流作用下的动力响应特征,并定量地分析了其对桩与承台连接节点混凝土浇筑质量以及结构耐久性的影响,为港珠澳大桥主体工程建设提供依据。
Based on the full-scale model process test of embedded platform bearing platform of Hong Kong-Zhuhai-Macao Bridge, this paper studies the dynamic response of wave-induced interaction between buried cap and pile using theoretical calculation and in-situ test monitoring. Theoretical calculation and analysis The dynamic response of cap and pile subjected to wave current is analyzed by the combination of fluid dynamics software Flunt and Sesam with general finite element software Ansys. Combined with in situ test and dynamic monitoring, The dynamic response of the piles and piles under the wave current is analyzed. The influence of the piles and piles on the quality of the concrete pouring and the durability of the structure are quantitatively analyzed, providing the basis for the construction of the main project of Hong Kong-Zhuhai-Macau Bridge.
