Deformation Characteristics and Influence Factors of a Shallow Tunnel Excavated in Soft Clay with High Plasticity
Table 2
Suggestion for construction of shallowly buried soft surrounding rock tunnel during atmospheric rainfall.
| Daily precipitation (mm) | Influence degree | Suggestions for construction |
| ≤4 | Small impact | Can maintain the previous state | >4 | Significant impact and 1-2 weeks of lag time | Shorten the excavation footage, reinforce the support structure, and strengthen deformation monitoring in the next 2 weeks |
