摘要
以修正应力法为依据,假设桩体在疏布状态时,其承载力达到单桩设计承载力极限值,在此前提出一种计算深厚软土地基中疏桩基础沉降的新方法,命名为疏桩极限法。通过工程实例分析,该方法在适宜的条件下是可行的。
Base on the methods of stress amendment in this paper,assumptions pile on the Sparse layout state,its carrying capacity reached Design limits the bearing capacity of single pile,on this premise raising a new method of settlement of dredging a deep pile foundation in soft soil,named sparse pile limit.Through the analysis of project,this method is suitable under the feasible conditions.
