风浪流对绞吸船定位桩的冲击研究

在全面分析风浪流对绞吸船定位桩的冲击荷载的基础上,对绞吸船施工中定位桩的动力响应提出了编程计算和有限元分析相结合的研究方法,即:通过编写程序计算定位桩在各种风浪流条件下的环境荷载,通过有限元模拟求解出定位桩在风浪流作用下的动力响应.采用该方法得出的结果与实际较为符合,对绞吸船的安全施工具有参考价值.

On spud impacted by wind, wave and current

Based on the analysis of spud loads under the combined action of wind, wave and current, this paper puts forward the method which combines programming calculations with finite element analysis on the spud dynamitic response in the wind, wave and current environment, i.e., gaining the spud loads under the combined action of wind, wave and current through programming calculation at first and then obtaining the dynamitic response of the spud by finite element analysis. The results from this method agrees well with the real case, so it may serve as reference for safe construction of cutter suction dredger.
