Abstract: On the basis of some analyses on distribution of rock mass fracture structures in permanent shiplocks of the Three Gorges Project, we have studied fractal values of fracture structures in and near the area where the shiplocks locates and in the first section every shiplock roon. All results identify that fractal feature exsits in the area and in sections every shiplock room. Fractal values are useful in selecting typical section in all shiplock rooms, which may be more reasonable than the general selection.

摘要： 本文对三峡工程永久船闸区断裂构造基本特性进行了分析,并运用分形理论对区内断裂构造的地表分布及船闸各闸首地质剖面上断裂构造分布的分维值进行了计算.结果表明,区内断裂构造具有分形特性,分维值可用于优选船闸典型断面以资进行岩石力学及工程进行研究,具有较强的实用价值.
