摘　　要：系统论述拉美地区高桩结构中常用的双向π形面板的结构特点和适用性,对其施工期和使用期的结构受力开展有限元分析,总结结构变形、受力分布特性和不同尺度参数对内力的影响规律,并对局部薄弱点提出加强措施。结果表明,与常规面板结构相比,双向π形面板使上部结构更轻便、整体性更好,在力学性能上也有进一步提升。研究成果验证了双向π形面板的技术可靠性和合理性。We systematically discuss the structural characteristics and applicability of the bidirectionalπ-shape slab commonly used in piled wharf structure in Latin America region,carry out the finite element analysis of the structural forces during the construction and the service periods,summarize the structural deformation,force distribution characteristics and influence law of different scale parameters,and propose the reinforcement measure for local weak point.The results show that compared with the conventional slab structures,the bidirectionalπ-shape slab makes the upper structure lighter and more integrated,and the mechanical properties are further improved.The results verify the technical reliability and rationality of the bidirectionalπ-shape slab.
