The selection range of the proposed restoration coefficient of Ye Si Bridge.
| Slope characteristics | Coefficient of normal restitution | Tangential coefficient of restitution |
| Smooth hard rock surface, paving surface, shotcrete surface, and masonry surface | 0.25∼0.75 | 0.85∼0.98 | Soft rock surface and strong weathering hard rock surface | 0.15∼0.37 | 0.75∼0.95 | The slope is stacked with stones | 0.15∼0.37 | 0.75∼0.95 | Dense gravel accumulation, hard soil slope, vegetation development, mainly shrubs | 0.12∼0.33 | 0.30∼0.95 | Dense gravel accumulation slope, hard soil slope, no vegetation, or a few weeds | 0.12∼0.32 | 0.65∼0.95 | On the loose gravel slope and soft upper slope, the vegetation development is mainly shrub | 0.10∼0.25 | 0.30∼0.80 |
