| Abstract: | On the basis of considering spatial co?operation action of piles?ring beam?connecting beam system, a new calculation method fitted for the actual state of double?row piles in deep foundation is proposed. In addition, based on Winkler foundation model a finite element structural analysis program is developed. According to the requirement of the information for construction, a feedback design theory is recommended. Finally, an engineering case is computed and used to verify the model . A parameter study is carried out to investigate their effects. The calculation results show that the proposed method is effective and some beneficial conclusions are obtained. |
