摘　　要：以北京地铁十号线某区间三联拱大断面隧道为例建立模型,采用有限元的方法模拟隧道施工过程,对施工沉降进行了超前预测,尤其对各个步序沉降比例进行了定量分析,并据此制定了合理的施工流程和减小沉降的技术措施。Using the tri-arch large-section tunnel in the metro section of Beijing subway, the paper establishes the model. It uses the finite element method to stimulate the construction of the tunnel and predicts the settlement. In particular, it makes a quantitative analysis of the settlement ratio of each step and draws up reasonable construction procedure and measures to decrease the settlement.
