摘要
根据分形理论，研究了成都、合肥粘土体裂隙效应中存在的分形几何现象，表明裂隙空间展布、极点分布、土样强度的尺寸效应等均具分形结构。计算结果表明，成都粘土的分维值普遍大于合肥粘土，同时还探讨了成都裂隙性粘土体变形模量E0与其空间展布分维值Dk的相关关系。
The fracture geometry properties in fissure effect of Chengdu clay mass are studied. It is found that there are fracture structure in fissure's distribution pole distribution and size effect for strength of clay sample. Results show that the fracture dimension of Chengdu clay is commonly larger than that of Hefei clay. Further,correlations between fractural dimension Dk of Chengdu fissure 's distribution and its deformation modulus E0 of clay mass are discussed respectively.
