摘　　要：文中以西安地铁六号线典型黄土梁洼地区暗挖隧道的竖井为背景,详细介绍了黄土地区暗挖竖井施工阶段受力规律,以分析暗挖竖井所需混凝土厚度及钢筋型号;通过荷载-结构计算模型,采用Midas gen结构分析通用程序对竖井受力进行内力分析,计算结果表明竖井深度28m处最大弯矩约为404kN·m,最大剪力约为400kN,根据计算结果,采用400mm厚混凝土主筋为φ28mm(附加钢筋)的钢架、φ12@100mm箍筋可满足设计要求,施工过程中对竖井仍采取监测及信息化施工等相关措施,以供类似暗挖竖井设计参考。This paper introduced the force law of the vertical shaft during the construction stagebased on the vertical shaft in loess area of Xi'an Metro Line 6 to analyze the concrete thickness and steel bar type of the underground vertical shaft.Midas software is used to analyze the force law through the load-structure calculation model.According to the calculation results of load structure model,the maximum bending moment of the 28m depth in the vertical shaft is about 404kN·m,and the maximum shear force is about 400kN.Moreover,the 400mm thickness of the lining thick would be satisfied with design requirement.In addition,monitoring and information is still needed during the construction stage.This paper mayprovide references for the similar projects.
