以青岛地铁3号线中山公园站1号风道工程为依托，通过理论计算与数值模拟相结合的方法，对浅埋暗挖大断面风道端墙进行支护优化分析，提出了全长注浆锚杆+钢筋带的支护方案。研究表明，优化方案的端墙最大变形值减小了19.3％，塑性区主要控制在端墙后方2 m范围内，起到了良好的加固效果。“,”Taking the Zhongshan Park duct 1 works on Qingdao Metro Line 3 as an example, the paper uses the method of theoretical calculation and numerical simulation, and optimizes the analysis of the support structure of the large section duct. The results show that the maximum deformation value of the end wall is reduced by 19.3% by using the optimized option, and the plastic zone is mainly controlled by the end wall in the 2 m range, which has a good effect.
