摘　　要：本文研究了现浇混凝土圆孔板的正交各向异性,通过有限元法对不同直径和不同间距的圆孔板进行了分析,计算归纳出了圆孔板的两个方向的刚度比,给出了两个方向的宏观弹性模量、剪切模量和泊松比的计算公式,该公式误差小,计算方便,为现浇混凝土空心板的计算和设计提供了理论依据。The orthotropy of cast-in-situ concrete hollow plate is studied in the paper. The rigidities in two directions of the plate with various diameters and various distances hollows are analyzed by FEM. The formulae to calculate the elastic modulus, shear modulus and poison ratio in two directions are given. They are easy to use and have small inaccuracy. The paper gives the theory basis to calculate and design the cast-in-place concrete hollow plate.
