摘要
利用有限元模型分析了青岛新建地铁8号线工程下穿既有地铁3号线的施工风险,给出了超前小导管加固的施工方案,并定量分析了施工对既有线路变形的影响。
Qingdao Metro Line 8 goes under the existing Metro Line 3,the finite element model is used to analyze the construction risk of the proposed subway line 8 going under the existing subway line,the construction measures for reinforcement of advanced small pipes and the influence on the existing subway line deformation is quantitatively analyzed.
