摘　　要：通过试验研究 ,提出了沉入式大圆筒抗倾计算的抗倾有效比和抗倾折算比新概念 ,指出了沉入式大圆筒抗倾计算的新途径。根据试验资料分析 ,提出了沉入式大圆筒抗倾比 η与相对沉入深度 h h0之间的关系式 ,可供沉入式大圆筒结构抗倾计算时参考。From test studies, a new conception about the effective ratio and converting ratio against overturning is proposed for anti-overturning calculation of the large-diameter cylinder and a new anti-overturning calculation method of the large-diameter cylinder structure is given. Based on the analysis of test data, the relation between the ratio against overturning of the sunk large-diameter cylinder, η,and the relative sinkage, h/h 0 is obtained which can be used in anti-overturning calculation of large-diameter cylinder structures.
