摘　　要：鉴于现行规范中重力式锚碇结构的稳定性计算未考虑基底前侧抗力,文章结合模型试验和有限元分析,通过强度折减法来获得重力式锚碇的三维稳定性安全系数,并结合苏锡常南部高速公路项目,开展了土体参数对重力式锚碇稳定性的影响分析,明确了各个土体参数的相对重要性。In view of the fact that the resistance in front side of the foundation is not considered in the stability calculation of the gravity anchor structure in the current code,it is necessary to combine the model test and finite element analysis,obtain the three-dimensional stability safety factor of the gravity anchor through the strength reduction method,and analyze the influence of soil parameters on the stability of the gravity anchor in combination with the south Suzhou-Wuxi-Changzhou expressway project.The relative importance of each soil parameter is clarified.

关 键 词：重力式锚碇结构 稳定性评估 强度折减法
