摘　　要：在考虑排桩 圈梁 连系梁空间协同作用的前提下 ,提出了一种更适合双排桩实际工作性态的计算方法。并根据信息化施工的要求 ,提出了实用的反分析计算理论。计算表明 。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.
