摘　　要：针对地铁车站使用模板台车进行二次衬砌施工时某些区段混凝土浇筑填充不均导致成形效果不好的问题,运用CFD方法研究现浇混凝土在模板台车与既有隧道壁间的扩散填充行为,将现浇混凝土视为不可压缩的非牛顿流体,采用VOF技术追踪混凝土在空气中的流动行为,以不同高度水平线上混凝土相的体积分数分布的波动程度为评价指标研究了混凝土黏度、进浆口布置数量、布置角度对填充性能的影响,提出合理建议,为类似工程提供参考。In order to solve the problem of poor forming effect caused by uneven filling of concrete in some sections when formwork trolley was used for secondary lining construction in metro station,the diffusion filling behavior of cast-in-place concrete between formwork trolley and existing tunnel wall was studied by CFD method.Cast-in-site concrete will be regarded as incompressible non-newtonian fluid,the VOF technology to track the flow behavior of concrete in the air,combined with the actual concrete structure viscosity range and vehicle,with different height of phase volume fraction distribution of level fluctuation degree as evaluation index to study the concrete viscosity,the arrangement of pulp inlet effect the performance of the fller amount,arrangement Angle,provide reasonable suggestions to serve as a reference for similar projects.
