大断面地铁车站新奥法施工监控量测

The new Austrian method construction monitoring measurement of large section subway station

基于某大断面车站施工,结合地下工程开挖施工监控量测,围绕周边位移、拱顶下沉以及钢格栅与钢拱架应力量测,进行了大断面隧道施工监控量测分析与结果处理,分析指出,当受到施工条件的限制,常规量测方案很难实施时,可适当采用可行的施工监控量测变通的方法。

Based on the some large section station construction, combining with construction monitoring measurement of underground engineering excavation, surrounding circumference displacement, arch settlement and measurement of steel grid and steel arch stress, monitoring measurement analysis and results treatment of large section tunnel construction monitoring measurement were carried out, which pointed out that when the construction condition was restricted, normal methods implemented difficultly, the flexible method of feasible construction monitoring measurement was adopted.
