摘要
本文通过对武汉地铁2号线区间隧道地表变形进行连续监测和监测数据的分析,得到了该工程条件下隧道地表沉降的变化规律,并采用有限元数值模拟方法对隧道开挖引起的地表沉降量进行了计算,其结果与监测数据吻合较好,验证了数值模拟方法所得到的地表沉降变化规律的准确性。该研究可为类似工程及地表变形的监控量测工作提供借鉴和指导。
By monitoring the ground surface settlements in Line 2 of Wuhan subway tube tunnel,this paper draws some conclusions about the ground surface settlements in the geological conditions through analyzing the monitoring data.Calculating the strata displacement during the tunnel excavation by numerical simulation indicates that the result is well consistent with the monitoring data,thus confirming the accuracy of regulations.This study can provide reference and guidance for the monitoring work in similar projects.
