After surface hardening with a 20-cm-thick layer of C20 concrete, the surface settlement is effectively controlled, and the uneven longitudinal settlement of the tunnel vault is improved.

用 20 cm 厚的 C20 混凝土层进行表面硬后，表面得到有效控，改善隧道拱顶的不均匀纵向。

Figure 10 shows that the longitudinal settlement of the tunnel vault in case 1 increases slightly after surface hardening, but the nonuniform settlement of the tunnel vault has been greatly improved.

图 10 显示，表面硬后，情况 1 中隧道拱顶的纵向有增加，但隧道拱顶的不均匀得到很大改善。
