摘　　要：针对承受移动或活荷载的板系结构，本文提出了一个修正的有限板块混合模型［１］［２］，推导了相应的广义荷载公式，用以建立板结构的影响面。对柱支承的无梁板系，本模型在提高计算精度、节约内存与机时等方面，效果尤为突出。For plate structures submitted to moving load, a modified mixedmodel for finite panel is presented and a series of formulas forcorresponding generalized load q is derived in this paper so as toestablish the influence surface of internal force in flat slabs.Numerical examples show that the modified model and formulas forgeneralized load presented in this paper have advantages overconventional models in high accuracy, need of less computer storageand computing time. They are effective especially for flat slabs.
