Calculations on Roughness of Rock Fracture Based on Image Processing

Abstract:

Joint roughness coefficient (JRC) is an important factor in the evaluation of the shear strength and deformation parameters of rock joints. This paper presents a method for measuring JRC of rock fractures based on digital image progressing technique. Though preprocessing of the rock fracture image, the skeleton of the fracture was got, the rough degree were analyzed and quantized by geometric parameters of the skeleton. By establishing the relationship between JRC and the rough degree, JRC will be got though the rough degree. This method improves automation degree and accuracy comparing to the previous methods. Finally this method was used to get the JRC of rock fracture in Jijicao, Beishan, Gansu province, where may be the high-radiation nuclear waste repository.
