Abstract Ten standard joint profiles proposed by Barton is taken as the research object. Firstly，relationship between four statistical roughness parameters and sampling interval of the ten profiles is analyzed，and roughness power parameters are calculated by using power function to describe the relationship. Secondly，new computational formulas of JRC are established based on the power roughness parameters，it makes the JRC computational formulas no longer depends on sampling interval of joint profiles. Finally，an approximate method to estimate JRC is proposed and any sampling interval in a certain scope can be selected to measure the joint profiles. The new method to calculate JRC value has a certain theoretical innovation and good application prospect.

Key words： rock mechanics rock joint roughness coefficient statistical parameters power parameter sampling interval
