摘要
运用商用数值模拟软件模拟隧道开挖施工过程,通过对大断面隧道开挖引起塑性区分布、地层分层沉降的数值模拟成果的分析,得出了在同一围岩条件下,采用不同的施工方法开挖隧道引起地表变形、塑性区分布、地层分层沉降的特性和机理,在此基础上提出了相关的施工技术措施,使隧道在整个施工过程中都处于安全可靠控制范围之内。
This paper introduces the two tunnel excavation methods and plans,model buildings and calculate results.By executing the survey of suface deformation,the paper recommends relying on the dynamic information feed back of deformation survey to ensure the construction safety and optimal design of tunnel excavation.Subsequently,corresponding technology measures of controling deformation in surface were proposed.
