摘要
针对境外开敞海域和强震区域码头结构设计的难点,以菲律宾马利万斯2×300 MW燃煤电厂码头工程为例,对结构承受波浪荷载及地震荷载特点进行分析,对不同工况下结构位移限制标准进行差异化选择,研究胶结地质对桩基适应性的影响,确定采用带下层靠系船平台的全直桩冲孔灌注桩码头结构形式。结果表明,该设计方案适应大浪、强震的环境影响,基础对地质条件适应良好,码头运行时结构位移控制良好。
In view of the difficulties in the structural design of overseas wharf in open sea and strong seismic areas,taking the project of 2×300 MW coal-fired power plant in Mariveles,Philippines as an example,we analyze the characteristics of the structure bearing wave load and earthquake load,carry out the differential selection of structural displacement limit standard under different working conditions,study the influence of adaptability of cemented geology to pile foundation,and determine to select the wharf structural form of the full straight piles with lower berthing and mooring platform.The results show that this design scheme can adapt to the environmental impact of large waves and strong earthquakes,the foundation can well adapt to the geological conditions,and the structural displacement can be well controlled during the operation period.
