Abstract:Stability analysis of gravity retaining wall was currently based on the assumption that the wall had no embedment depth. The effect of earth berm was usually neglected. The present work highlighted the importance of embedment depth when assessing the seismic stability of gravity retaining walls with the pattern of pure rotation. In the framework of upper bound theorem of limit analysis, pseudo-static method was applied into two groups of parallel rigid soil slices methods in order to account for the effect of embedment depth on evaluating the critical acceleration of wall-soil system. The present analytical solution is identical to the results obtained from using limit equilibrium method, and the two methods are based on different theory backgrounds. Parameter analysis indicates that the critical acceleration increases slowly whenthe ratio of the embedment depth to the total height of the wall is from 0 to 0.15and increases drastically when the ratio exceeds 0.15.

 

Key words: gravity retaining wall; embedment depth; seismic rotational stability; upper bound analysis; parallel rigid soil slices
