摘　　要：考虑桩侧土体的应力松弛和土抗力重叠效应，提出了桩侧土抗力群桩效率的计算式。该式考虑了土质的影响，适应性强。计算结果接近于试验实测值。A group efficiency formula of lateral earth resistance, which is based on analysis of lateralearth stress relaxation and earth resistance overlap effect is presented in the paper. The formula isadaptable and the result of calculation approaches to the data from experiment because ofconsidering influence of earth condition.
