摘要
以杭州地铁7号线建设三路站—耕文路站区间盾构下穿2号线既有建设三路站为背景,采用数值模拟的方法,研究分析新建地铁车站基坑开挖和新建区间盾构下穿既有车站结构过程中,既有车站结构和盾构隧道的变形趋势及最大沉降区域的分布概况;结合相关工程经验,提出盾构隧道下穿既有车站控制措施。
Taking an example of shield tunneling underpassing the existing metro station between Jianshesanlu Station-Gengwenlu Station of Hangzhou Metro Line 7,and by using the numerical simulation,this paper studies and analyzes the deformation trend of existing station structure and shield tunnel as well as the distribution of maximum settlement area in the process of foundation pit excavation of new metro station and shield tunnel under existing station structure.Based on the engineering experience,it puts forward the control measures of shield tunneling under passing the existing stations.
