| 摘 要： | 以工程实例为研究对象,依据实际结构尺寸建立透空堤的有限元模型。基于有限元和动力响应的基本原理,应用有限元软件ANSYS对透空堤进行静力分析、模态分析和功率谱密度随机振动分析。结果表明,需要加强对透空堤桩基嵌固点处以及海侧第1、第3榀架桩基的应力防护,以提高透空堤的安全性。同时,通过比较可知,波浪荷载引发透空堤共振时,桩顶面和泥面处节点位移超出了中国船级社规定的限值,出现安全隐患,为此提出加大桩径、桩周填石以及桩内灌注混凝土等措施,以保障透空堤的安全性。

| Abstract: | With practical projects as examples,the models for finite element analyses were established according to their actual sizes.Based on finite element and dynamic response of the basic principles,static analysis,modal analysis and the PSD random vibration analysis were carried out through the finite element analysis software ANSYS.The results of the analyses prove that it is needed to strengthen the protection of the permeable pile mounted points and enhance the permeable breakwater safety.At the same time,whe... |
