Abstract (English): For the sea area where the cross sea bridge is located, it is faced with the threat of severe marine environment, such as strong typhoon, big wave and torrent, and the structure adopts high pile cap pile group foundation. When the structural safety check is involved, it is impossible to use the standard or empirical formula to calculate the wave current force. Therefore, a 1:40 scale overall physical model experiment was adopted to demonstrate the influence of wave and current forces on bridge foundations (pile cap and pile groups) through a combination of multiple factors such as wave height, period, water level, and scouring depth. The variation law between multiple factors and structural wave and current forces was revealed. At the same time, it is convenient for engineering applications. By utilizing the results of this study, as well as similar engineering projects such as the stress test results of the bridge foundation at the island bridge junction of the Shenzhen-Zhongshan Link, the empirical formula for the wave and current forces on the foundation structure has been further fitted. The results can solve practical engineering problems, and provide basic data and reference for similar engineering design. [ABSTRACT FROM AUTHOR]
Abstract (Chinese): 跨海大桥所在工程海域面临强台风及其引起的大浪、急流等恶劣海洋环境威胁, 且桥梁结构采用大尺度高 桩承台群桩基础, 涉及结构安全校核时, 无法利用规范或经验公式计算其受到的波流力。因此采用了比尺为1:40的整体 物理模型试验方法, 通过波高、周期、水位、冲刷深度等多因素影响的试验组合, 论证桥梁基础 (承台和群桩) 受 波流力的影响, 揭示了多因素影响与结构受波流力之间的变化规律。同时为了便于工程应用, 利用本次成果, 以及 类似工程——深中通道岛桥结合部桥梁基础受力试验成果, 进一步拟合了基础结构受波流力的经验公式, 成果不仅 解决工程实际问题, 也可为类似工程设计提供基础数据和参考。 [ABSTRACT FROM AUTHOR]
