海洋桥梁波流力作用与基础冲刷问题及对策研究
Wave Current Force Action and Foundation Scour of Marine Bridges
随着海洋桥梁不断向深海延伸，桥梁基础波流力作用与基础冲刷问题已成为威胁桥梁安全的主要因素。为了确保海洋桥梁设计的合理性以及建设运营的安全性，本文系统地梳理了海洋桥梁在波流力作用与基础冲刷方面所面临的主要问题，进而有针对性地提出了海洋桥梁需要在高精度预测方法、环境预报和预警系统、环境多因素耦合作用、冲刷数值模拟技术、波浪力计算方法等方向发展。研究表明，波流力作用与基础冲刷研究是海洋桥梁安全的重要保障，研究从宏观管理、行业应用、学术技术三个层面对当前问题提出了对策。
With marine bridges extending to the deep sea, wave current force action and scouring on bridge foundations have become the main factors threatening bridge safety. To ensure the design rationality as well as construction and operation safety of bridges, this paper sorts out the major problems faced by marine bridges in terms of wave force action and foundation scour, and proposes that marine bridges should be developed in high-precision prediction method, environmental prediction and pre-warning systems, research on multi-factor coupling effect of environment, scour numerical simulation technology, and wave current force calculation method. Furthermore, countermeasures are proposed from the aspects of macroscopic management, industrial application, and academic technology.
