岩体是自然界中具有一定结构特征的地质体,内部发育有各种类型的结构面,如层面、节理、断层、裂隙、不整合接触面等。结构面粗糙度对岩体的变形、强度以及渗流特性具有直接影响,该领域的研究一直作为岩土工程与地质工程学科的热点问题,受到国内外专家的广泛关注。然而,目前结构面粗糙度的数据采集和评价方面仍存在以下不足之处:(1)采集装备落后,范围小,试验周期长,不能满足岩体稳定性的快速评价要求;(2)评价方法对采样方向、采样尺寸以及
Rock mass is a kind of geological body with some structural features in nature. There are various types of structural surfaces such as bedding plane, joints, faults, fissures and unconformities in the interior. The roughness of structural surface has a direct impact on deformation, strength and seepage characteristics of rock mass. The research in this field has been a hot issue in geotechnical and geo-engineering disciplines, and has been widely concerned by domestic and foreign experts. However, the following shortcomings still exist in the data acquisition and evaluation of the structural surface roughness: (1) the backward collection equipment, small scope, long test period, can not meet the rapid evaluation requirements of rock mass stability; (2) For sampling direction, sample size as well
