Turbulence Effect on Slope Stability of an Earthen Levee Strengthened by HPTRM Under Overtopping Conditions

Original paper


It is important to evaluate the slope stability of levees during the hurricane overtopping involving storm surge and wind generated wave conditions. The effect of turbulence on the slope stability of an earthen levee strengthened by high performance turf reinforcement mat is investigated in this study for the cases including storm surge, wave overtopping, and combined storm surge and wave overtopping conditions. The turbulence is treated as a random shear force starting from the front of the crest and moving to the toe of the landside of the earthen levee. In addition, the shear stress produced by the wave is also considered. The results show that turbulence has strong influence on the slope stability in the storm surge and combined storm surge and wave overtopping conditions. It is found that the peak turbulent force has much stronger effect on the factor of safety than the peak wave force in the case of a small peak wave force.
