抗浮锚杆用于解决地下工程抗浮问题现已日益普遍和成熟,但其设计和施工还没有规范可循。通过理论计算锚杆变形,结合深圳市地下工程实例,对抗浮锚杆进行有限元模型分析及试验研究,得出抗浮锚杆的变形值与理论计算值较接近,并提出较为合理的锚杆允许变形值。 Anti-floating anchor used to solve the problem of anti-floating underground engineering has become increasingly common and mature, but the design and construction of norms to follow. Through the theoretical calculation of the deformation of the anchor bar, combined with the case study of Shenzhen underground engineering, the finite element analysis of the anti-floating anchor rod and the experimental study show that the deformation value of the anti-floating anchor rod is close to the theoretical calculation value, and a more reasonable anchor rod Allow the deformation value.
