根据Weierstrass函数人为地建立具有分形结构的节理模型来模拟节理剖面的粗糙性，通过试样的单轴压缩实验，在弹性理论的框架内对实验数据进行了统计分析。结果表明分形维数成为反映节理变形、强度、应力状态等的恰当统计特征量，这为研究岩石力学性质提供了一个新的方法。
Based on the Weierstrass function, a joint model with fractal structure was established to simulate the roughness of the joint section. The experimental data were statistically analyzed by the uniaxial compression test of the specimen within the framework of the elastic theory. The results show that the fractal dimension becomes an appropriate statistical feature to reflect the deformation, strength and stress state of joints, which provides a new method for studying the mechanical properties of rocks.
