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 the plate structure subjected to moving or live loads, a modified finite plate mixing model [1][2] is proposed in this paper. The corresponding generalized load formula is deduced to establish the influence surface of the plate structure. For column-supported beamless plates, this model is particularly effective in improving calculation accuracy and saving memory and machine time.
