【Abstract】 A method for numerical simulation the distribution of subgrade reaction is proposed in the paper. It is based on the concept of the soil?foundation interaction. The proposed method is adopted to analyze structures with typical foundation. Then the results are compared with that of the used models:the Winkler model, elastic half space model, and finite compression model. The results have shown that it is very close to that of the finite compression model. The proposed method is easily extended to simulate the subgrade reaction of complex foundation.更多还原
