摘要
为了解富水软岩地层中暗挖隧道施工引起的地表沉降特征,结合成都地铁某盾构区间地面沉降的工程实例,采用现场监测数据分析与数值模拟计算相结合的方法,分析地下水渗流作用对地表沉降的影响,提出了其影响因素及应对措施,为类似工程提供参考依据。
To illustrate characteristics of ground subsidence caused by construction of dark excavated tunnel with rich water and soft rock stratum,this paper combines the ground subsidence in a shield section of Chengdu subway,and uses the method of field monitoring data analysis with numerical simulation calculation to analyze the influence of groundwater seepage on ground subsidence,and puts forward influential factors and countermeasures to provide reference basis for similar projects.
