摘　　要：为建立薄板内力的影响面,作者首次提出矩形宏单元的内蕴模型,并推导了相应的广义荷载公式。算例表明,本文方法具有计算精度高、占用内存少等优点,对承受移动荷载的板—梁—柱结构,诸如双向连续桥面板、高桩码头无梁板等效果尤为突出。To establish the influence surface of resultants R for thin plates, a intrinsic model of rectangular macro element is proposed and a number of formulae for generalized distributive loadings are derived first in this paper which has advantages in high computational accuracy and low memory space, especially used in plate-beam-column systems subjected to moving load, such as two-dimentional continuous plates in highway bridge and flat slabs in piled jetty engineering.
