    Three Dimension Stability Analysis of Shenyang Subway Tunnel Excavation Based on FLAC3D

      摘要
    • 摘要: 以沈阳地铁1号线为背景,根据沈阳地质资料,运用FLAC3D建立了隧道开挖模型,分别对喷射混凝土预支护和混凝土衬砌进行了研究,分析两者对土体竖向位移的影响,建立了隧道开挖进度和土体沉降之间的关系,同时得出喷射混凝土预支护和混凝土衬砌厚度变化对支护拱顶和地面沉降量敏感度不同的结论.

       

      Abstract: Ground settlement and tunnel stability problem caused by tunnel excavation are two key problems of subway tunnel construction.Based on the background of ShenYang subway No.1 Line, according to geological data, three dimension numerical model of tunnel excavation is established.To study soil settlement with excavation process more exactly, shotcrete and concrete liner are studied respectively.The relationship between soil settlement and excavation process by using different support thickness is established.
