摘　　要：将高密度聚氯乙烯塑料球与混凝土楼板结合,形成新型混凝土塑料填充结构板。相对于传统的实心混凝土板减轻了自重,节约了建筑的成本,增加了屋面板跨度,优化了基础与受力构件设计,以及有利于建筑构件温度管理等等。采用大型分析软件ANSYS对新型混凝土塑料填充结构板进行静力计算分析,得到了该结构面荷载-变形关系以及其应力和变形云图。计算结果表明:混凝土塑料填充结构板的承载力比同尺寸的一般空心板大,5m×1.9m×0.23m的混凝土塑料填充结构板其最大承载力为1 087. 3kN,为此类混凝土塑料球填充板的承载力分析和实际应用提供理论依据。The high density polyvinyl chloride plastic ball is combined with concrete to form a new type of hollow slab,that is biaxial hollow slab.Compared with the traditional solid concrete slab,it reduces the weight,saves the cost of the building,increases the span of the roof slab,optimizes the design of the foundation and stress components etc. In this paper,an analysis software ANSYS is used to calculate and analyze the static force of a new type of biaxial hollow slab,and the load-deformation relationship of the slab and its stress and deformation nephogram are obtained. The calculation results show that the bearing capacity of biaxial hollow slab is larger than that of general hollow slabs of the same size.The maximum bearing capacity of biaxial hollow slab with 5 m × 1. 9 m × 0. 23 m is 1 087. 3 k N,which provides a theoretical basis for the bearing capacity analysis and practical application of this kind of biaxial hollow slab.
