Analysis on the Influence of Anchor Rod Layout Forms on the Reinforcement Effect of Multi-stage Slope
摘要
Abstract
In order to study the effect of slope reinforcement in different anchor rod layout forms,a numerical calculation model for the slope was established by using finite difference software FLAC3 D,based on the deep cut slope of Huashanjie-Limu Highway of Zixi.The effect of anchor rod layout forms on the distribution law of the anchor axial force and the stability of deep excavation cut slope was analyzed combining with the site test data.The results show that the axial force of the anchor rod does not distribute uniformly along its length;with the increase of anchor length,its reinforcement effect can be improved significantly,and the reinforcement effect of the anchor rod with same length and layout position is not affected by the overall layout form of the anchor rod;anchors with the same length but in different positions play a similar role in the limit state;when the total length of anchors remains constant,the change of anchor layout forms has little influence on the stability of slope.关键词
