The advanced small pipe grouting is a kind of valid way to reinforce geologic strata in the shallow tunnel construction. However, there is large divergence in handling the strata when establishing the finite element model.
在浅埋暗挖法隧道修建中超前小导管注浆是一种有效的地层加固方式,但在利用有限元建立地层模型中如何处理该层存在很大的分歧,在不同的地质条件下,采用的不同注浆材料、注浆机械、注浆压力,在建立模型时,加固区域的物理力学参数有很大的差异,为隧道的有限元分析造成了很大的困难。
