Anisotropy, scale and interval effects of natural rock discontinuity surface roughness

  • 摘要: 为了研究天然岩体结构面粗糙度评价结果影响因素,以重庆武隆地区大尺寸岩体结构面为例,运用三维激光扫描技术,基于Grasselli改进法描述粗糙度在不同采样方向、尺度与精度下的变化规律。结果显示:所选用的天然岩体结构面具有明显的各向异性、正尺寸效应和间距效应,因此在进行粗糙度评价时,采样方向务必与剪切方向保持一致,采样尺寸与采样间距应大于等于和小于等于有效采样尺寸与间距;为便于不同评价方法间结果对比,应保证在相同的采样参数下开展研究。
    Abstract: To estimate the influence factors on the natural rock discontinuity roughness, taking an in-situ large scale rock collected in Wulong County, Chongqing City as an example, the variation rules of roughness under different sampling directions, sizes and precisions are analyzed by using the 3D laser scanning technology, and Grasselli’s method is improved through discretization of rock discontinuity into a large amount of quadrangular tiny planes rather than triangular planes. The results show that the natural rock discontinuities considered herein are characterized by obvious anisotropies, positive scale effects and interval effects. Therefore, the sampling direction with respect to roughness data acquisition should be kept the same with the shearing direction (direction of rock mass movement) in the procedure of roughness evaluation. In addition, the sampling size is specified to be equal to or larger than the effective sampling size, while the sampling interval should be equal to or less than the effective sampling interval. For the convenient comparison among the assessed results by different methods, this kind of study should be performed under the same sampling parameters including sampling directions, sizes and intervals.
