非连续变形岩石断裂分析中的一种全长剪切锚杆
A full-column shearing anchor bolt of discontinue deformation analysis for rock failure
摘要
Abstract
From the anchoring way, anchor bolt has been divided into two kinds:end anchorage mode and full-column anchorage mode. As an important anchor bolt type of engineering support, full-column anchorage bolt has a broad application prospect. Only the end anchorage bolt is used in discontinuous deformation analysis (DDA), and its extended procedure DDARF method, while, the axial role of bolt is considered and the lateral limit of the bolt’s anchor force to rock masses is ignored. In order to better understand the bolt support mechanism, and to consider the shear effect of bolt, a new bolt form of DDARF is put forward-full-column shearing anchor bolt. The surrounding rock’s stability of a highway tunnel is analyzed with this improved full-column shearing anchor bolt, the results are compared with that of end support anchor bolt;and show that, this full-column shearing anchor bolt is effective, and has better anchorage effect than end anchorage support.关键词
