目前国内码头结构形式多为板桩墙,受墙身高度限制,只适用于中小码头建造。遮帘式板桩结构,在前墙后加入一排桩,极大改善了前墙受力,使码头泊位向大型深水化提供了可能。该结构无成熟的设计方法,为了更准确的设计及改造已有码头,需对常规设计方法进行验证。结合京唐港#32码头遮帘桩工程,采用ANSYS对其进行数值模拟。计算表明,在正常设计工况下,加桩后前墙弯矩减少了约70%,负弯矩减少了约10%。加遮帘桩前后,后墙受力变化不大。数值计算与监测结果基本吻合,证明遮帘桩是一种可行的支护方式。
At present, most of the wharf structures are sheet pile walls, which are limited by the height of the wall and are only suitable for the construction of medium and small wharves. Shaded sheet pile structure, adding a row of piles behind the front wall, which greatly improves the front wall force, the berth to the large-scale deep-sea provides the possibility. The structure of immature design methods, in order to more accurately design and transform the existing terminal, the conventional design methods need to be verified. Combined with the curtain pier project of # 32 pier in Jingtang Port, ANSYS was used to simulate it. The calculation shows that under normal design conditions, the bending moment of the post-pile wall is reduced by about 70% and the negative bending moment is reduced by about 10%. Add shadow curtain before and after the wall force little change. The results of numerical calculation and monitoring basically agree with each other, which proves that shading piles are a feasible way of supporting.
