摘要
RQD作为工程实际中评价岩体性质的方法,应用已相当广泛,并已列入有关规范。然而,由于传统Deere定义的RQD在实际应用中存在很多问题,所以引入了不同阈值下的广义RQD的概念,并与不连续面三维网络模拟技术相结合,应用于岩体的稳定性评价,取得了较好的效果。
RQD has been used widely in projects to evaluate the rock mass properties. It has been listed in the relevant codes. However, because traditional RQD by Deere has many limitations in applications in projects, conception of generalized RQD under different threshold values was introduced. It has been applied to evaluate stability of rock mass, combine with 3D network simulation technique of discontinuities. And better RQD results have been obtained with its use in projects.
