| 摘 要： | 以分形维数定量描述岩石节理面粗糙性，通过剪切实验分析研究节理剪切强度、法向应力和节理面分维的相互关系，建立了能够体现节理粗糙性和节理剪胀效应的节理剪切强度表达式，提出了适用于粗糙节理岩体的库仑强度的修正公式，为更深入、更准确地研究岩石节理剪切强度和岩体结构稳定性提供了新的方法。

| Abstract: | The paper quantitatively stated the roughness of the rock joints with the fractal dimension. With the shearing tests, the paper studied the relationship between the joint shearing strength, normal stress and joint fractal dimension. Theoretically, a joint shearing strength formula was set up to show the joint roughness and the joint shearing swelling effect and a revised formula of the Coulomb strength suitable for rough joint rocks was derived. |
