施工期天鲸号适应能力分析

天鲸号绞吸式挖泥船在海上进行疏浚作业时,波浪要素需要满足一定条件,才能保证安全施工。为了确定防波堤修建后掩护区的波浪条件是否满足天鲸号的施工要求,采用数学模型计算了某集装箱码头工程在不同节点时防波堤掩护区的波浪条件,对天鲸号挖泥船适应能力进行分析,并给出如果不满足施工要求时防波堤需延伸的长度。结果表明:波浪数值模拟技术可以很好地为挖泥船海上安全作业提供可靠的依据,避免风险。

Analysis of adaptability of Tianjinghao during construction period

When Tianjinghao is dredging at sea,the wave parameters should satisfy certain conditions to ensure the safety of construction.In order to make sure whether the wave conditions sheltered by the breakwater meet the construction requirements of Tianjinghao,numerical model is used to calculate wave parameters in breakwater shelter with different progress node of a container terminal project,analyze adaptability of Tianjinghao,and calculate breakwater length need to extend to meet the construction requirements.The results show that the wave numerical simulation technology can provide a reliable basis for safe operation of dredger at sea and avoid risks.
