摘要
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。
The uplift anchors for the buoyancy design in underground projects have received wider applications and become increasingly matured.However,there are no current design and construction code available for the guidance.This paper presents an allowable deformation criteria for the uplift anchors throughout the theoretical analysis of the deformation of the uplift anchors.A case history of the uplift anchor in an underground project Shenzhen is also presented.The deformation of uplift anchors is analyzed by using finite element analysis.The deformation of the uplift anchors in the numerical analysis is obtained and is found to be close to the analytical value.
