摘要
文章通过对比大管棚和超前掌子面加固两种超前支护措施,就其抑制掌子面挤出效果对比分析得出超前掌子面加固的效果高于大管棚,进一步说明不同超前支护措施在控制隧道大变形过程中的作用机理。
The article compares the two advanced support measures of the large pipe shed and the advance face reinforcement,and compares and analyzes the suppression effect of the face extrusion.It is concluded that the effect of the advance face reinforcement is higher than that of the large pipe shed,which further explains the different advance supports mechanism of protective measures in the process of controlling large tunnel deformation.
