摘要
城市中修建隧道不可避免会对地面建筑产生影响,所以需要对隧道施工产生的地表位移进行研究。以双孔大小隧道为例,垂直穿越地表基础,利用Midas/gts模拟两个隧道施工对地表基础的影响,分别分析出了施工沉降和固结沉降。结果表明,大小隧道同时施工沉降值比单独隧道施工时大,固结沉降在总沉降中占主要比例,大隧道施工对沉降的影响比小隧道大,总沉降最大值出现在大小隧道交界区域。需要定期监测。
In the city,building the tunnel will inevitably affect the ground buildings,so tunnel construction of surface displacement needing to be studied.Taking double orifice size tunnel as an example,vertical through the earth＇s surface,using Midas / GTS simulates the influence of both the foundation of the earth＇s surface caused by tunnel construction,analysing the construction settlement and consolidation settlement respectively.Results show that two tunnel construction settlement value is larger than the single tunnel construction at the same time,consolidation settlement is in a major proportion of the total settlement,tunnel construction settlement is larger than that of small tunnel,the maximum of total settlement appears during two tunnel border area.
