摘要
通过新宝塔山隧道施工过程对既有宝塔山隧道的影响进行了数值模拟,并实测了新隧道开挖过程中既有隧道衬砌结构的变形和衬砌混凝土的应变变化情况。数值模拟结果和现场实测数据表明,既有隧道衬砌结构的变形和衬砌混凝土的应变变化较小,新隧道施工对既有隧道影响不明显,对后续工程施工有指导意义。
The paper has the numerical simulation of the influence of the construction process of the new Baotashan tunnel on the existing tunnels of Baotashan,measures the deformation of the lining structure of the existing tunnels and the strain variation of the lining concrete in the excavation process of the new tunnels,and proves by the numerical simulation results and the data of the measurement that the deformation of the lining structure of the existing tunnel and its strain variation of the lining concrete are little and the new tunnel project does not have the obvious influence on the existing tunnels,so as to have the direction significance for the following projects.
