摘　　要：断层泥的瞬时力学性质和蠕变特性与含水量关系密切，其力学参数随含水量增加而减少，呈负指数函数关系。界限含水量划分具有很大的意义，某地ｆ２４６断层泥界限含水量为８％～１０％。The instantaneous mechanical properties and creep behavior of fault gouge are closely related with its water content. Its mechanical parameters will decrease with increasing water content and the relationship between them shows a negative exponential function. Demarcation of water content has great practical significance. The demarcated water content for f 246 gouge in a studied zone is 8 to 10 percents.
