新型带有水平撑的全直桩码头结构的应用

Application of new vertical pile wharf structure with horizontal braces

针对目前很多地质条件较好的地区存在斜桩沉桩困难并且全直桩结构水平荷载抵抗能力不足的问题,通过对比计算,探讨一种新型带有水平撑的全直桩码头在实际工程运用的可能性。通过在传统的全直桩结构间增加水平撑以形成互连结构,可以显著提高结构整体刚度,从而弥补全直桩水平荷载抵抗能力不足的缺陷,同时避免了斜桩施打。研究成果对于类似地区方案选择具有指导意义。

To increase the horizontal resistance of vertical pile wharf structure and avoid the difficulty in piling,we explore the possibility of using a new vertical pile wharf structure with horizontal braces based on comparative calculations.Adding the horizontal bracing between the vertical piles to form an interconnected structure,we can remarkably improve the overall rigidity of the structure to make up for the lack of horizontal load resistance of the vertical pile.Meanwhile,we avoid the difficulty in piling.The research result may serve as reference for the scheme selection in similar regions.
