The seismic stability of reinforced soil wall is a crucial field in the geotechnical engineering field when it is situated near the coastal area and subjected to coupled action of water waves and earthquake loading. The present study investigates the seismic internal stability of waterfront reinforced soil wall under the influence of non-breaking water waves considering cohesive frictional backfill. Limit equilibrium approach based on pseudo-static method is employed for assessing the equivalent tensile reinforcement coefficient and the length of each reinforcement layer embedded within the soil wall. Design charts are prepared for different soil and wave parameters like cohesion of soil, internal friction angle of soil, horizontal and vertical seismic acceleration coefficient, pore pressure ratio, height of water on both sides of wall, height of wave, duration of wave generation and wavelength. From the investigation it is observed that length of reinforcement within the failure zone is going to reduces with increase in the internal friction and cohesion values of soil. The stability of reinforced soil wall decreases significantly with increasing the seismic acceleration in both directions thus requiring more length of reinforcement and tensile strength to maintain the stability of soil wall. Present research addresses a critical gap by exploring the combined effect of seismic and wave loading on the internal stability of waterfront reinforced soil wall. Comparison of results with previous studies along with limitations are also highlighted in the present study.
