摘要
以贵阳地铁区间矿山法隧道下穿市政公路箱涵为依托,根据提出的设计方案,运用MIDAS/GTS有限元软件建立模型,分析了隧道开挖过程中箱涵的沉降变形规律以及隧道自身结构的稳定性,确保下穿施工时区间隧道的施工安全和箱涵的结构稳定,为后续工程的设计与施工提供借鉴。
Relying on the Guiyang metro section tunnel under the municipal highway box culvert,based on the proposed design plan,using MIDAS/GTS finite element software to establish a model,analyze the settlement and deformation laws of the box culvert during tunnel excavation and the tunnel itself The stability of the structure ensures the construction safety of the interval tunnel and the structural stability of the box culvert during the underpass construction,and provides reference for the design and construction of subsequent projects.
