摘　　要：从理论公式出发 ,运用实体深基础法计算群桩极限承载力 ,按静力法计算单桩极限承载力 ,反算出了不同影响因素下的群桩效率系数 ,通过对其分析研究后 ,对实体深基础法的适用性进行探讨 。In this paper,equivalent deep foundation method is used to calculate the bearing capacity of grouped piles and static method used to calculate that of single pile based on theoretic formulas.Then,the coefficient of group efficiency in baring capacity of grouped piles under different effect factors is worked out.Through study and analysis to it,the authors discuss the serviceability of equivalent deep foundation method and put froward their opinions and advices to some principle problems existing in pile foundation engineering design.
