| 摘 要： | 基于弹性梁理论和Boussinesq解，将弹性地基上的十字交叉梁基础分为两个方向的梁，并将上部结构简化为等效刚度板，通过梁与地基以及梁柱板之间的力与位移平衡协调分析，得到了考虑上部结构刚度时十字交叉梁基础与地基共同作用的半数值半解析解，算例表明，文中方法精度可靠，计算未知量少，便于实际工程采用．

| Abstract: | In this paper, by taking the rical solution to the interaction between superstructure rigidity into consideration grillage beam foundation and subsoil is , a semi-analytical and semi-numeobtained based on the elastic beam theory and the Boussingesq solution. In the process of working out the solution, the grillage foundation on elastic subsoil is regarded as a composite system of beams in two directions. The superstructure is simplified as a plate with equivalent rigidity, and the force and the displacement among beams, slabs, columns and the ground are compatibly analyzed. It is proved by numerical examples that the proposed method is of high precision with less unknown data and it is convenient for practical engineering. |
