摘　　要：针对现浇混凝土空心楼盖的分析问题,以经典薄板理论为基础,通过构造比拟正交异性板,提出了解决这类问题的一种新方法。在此基础上,进行了相应的公式推导,并对四边简支的空心楼盖进行挠曲微分方程求解。结合算例,采用比拟正交异性板方法,运用有限元分析软件对该方法分析结果精度进行了检验。结果表明,该方法计算空心楼盖内力和变形有较高的计算精度,能够满足工程应用的要求。Based on the classical theory of elastic plate, and using the principle constructional orthotropie plate, a new method of analysis for the cast-in-situ concrete hollow floor is proposed. In this method, the corresponding equation was educed, and the basic equation for dending plate with simply supported on four sides was calculated. Through the testing example ,the calculation accuracy on the internal force and deformation using this method was verified by applying the finite element analytical implementation.
