沉箱式防波堤的稳定性分析

The Stability Analsis of Caisson Breakwater

运用有限元方法和动力分析方法,对沉箱式防波堤在近破波作用下的动力响应进行了研究。在确定滑移位移和转角为防波堤的主要参考动力响应参量的情况下,对能够产生运动的滑移和摇摆两种运动形式进行了动力分析,并提出了滑移位移和转角随时间历程的变化趋势。

In the traditional design method of breakwaters, breaking wave pressure which apply to stability checking computations is considered as a static force, and dynamic characteristics of breaking wave and breakwater motion are neglected. In this paper, the dynamic responses of caisson breakwater under wave forces are studied through finite cell simulation and dynamic analysis means. And in this paper, slippage and waggle two athletics forms which can bring slipping replacement and corner to be mostly consult forward to slip to move the variety trend that moves athletics are put up dynamic analyzing by confirming dynamic response parameter of the breakwater. Put and acts any time turn the Cape a process.
