River downstream always suffer shock because of the wind or the ships sailing from the waves caused by impact.
The mainly parameter is the height for the design of resisting the shock.
Our test can help us to reciprocate by observing the impact of the role of the waves to define these curves reflects the inclination and water permeability associated with gabion box stability limit.
Thickness 0.15 meter Reno Mattress graph(the actual scale)
Reno mattress height(m)
These experiments show experimental Reno Mattress/Gabion layer:
1.Embankment slope of 1:3 Reno Mattress, height of 0.15m of Reno Mattress, 30% reduction in the height of the waves hit, reduced by 50%-80% of the reaction force.
2.Embankment slope of 1:1.5, height is 0.15m and 0.25m of Reno Mattress, 40% reduction in the height of the waves hit, reduced by 50%-80% of the reaction force.
3.Embankment slope of 1:1.5, height of 0.15m of Reno Mattress, plus filling mastic asphalt in surface, 40% reduction in the height of the waves hit, reduced by 10% of the reaction force.
Comparing the use of Reno Mattress and loose stone of the embankment protection works, we fiind that the wave height is 0.75m and the embankment slope of 1:1.5, the 0.15m height of Reno Mattress to stabilize structure. And the same situation, the loose stone thickness is 0.6-0.74m, the wave height is 1.25m and Embankment slope of 1:1.5, thickness is 0.25m to stabilize the structure, but the loose stone thickness is 0.95-1.15m.
