| Abstract: | On the basis of analysis by mechanics and adopting optimization concept, the mechanical model of mat foundation under silo-cell group was established for expressing the compression forces under foundation surface and the method of dealing with external loads were put forward in this paper. In considering one row and two rows of silos, the minimum foundation area was taken as a target function. In order to meet the needs of structural safety and the requirements of construction an inverse step by step search method was introduces. In addition,an optimum design program was also given for computer use. |
