水平力作用下全直桩高桩码头斜撑作用影响分析

Analysis of Inclined Braces of Vertical Pile Berth Structure under Horizontal Force

针对较大水位差作用情况下,全直桩高桩梁板式码头结构的水平荷载抵抗能力不足的问题,提出了一种斜向支撑的结构形式。采用有限元分析方法,分别对不设支撑和设置斜向支撑两种结构进行计算,对比分析其在水平力作用下结构的变形和内力特征。结果表明斜向支撑能有效的提高全直桩高桩码头的水平抗力。

An inclined brace structure is proposed to raise the horizontal load resistance of beam slab berth structure supported on vertical piles under the condition of large water level difference. The finite element method has been used to calculate the structures with/without inclined braces respectively, and compare the characteristics of structural deformation and internal force under horizontal force. The results show that the inclined braces can improve effectively the horizontal resistance of vertical pile berth structure.
