Dear Sudesh: Please look at the following journal papers which contain references to seismic failures of retaining walls:

1) Huang, C.-C., Chen, Y.-H. (2004). Seismic stability of soil retaining walls situated on slope, J. Geotech. Geoenviron. Eng., ASCE, 130(1): 45-57.

2) Okamura, M. (2007). A simple method for evaluating seismic failure potential of retaining walls on slopes, Struct. Eng. Earthquake Eng., 24(1): 31s-37s.

You may also want to read the following conference paper which refers to laboratory tests:

3) Elms, D.G., Richards Jr., R. (1990).Seismic design of retaining walls, Geotechnical Special Publication 25, ASCE, pp. 854-871, Design and Performance of Earth Retaining Structures - Proceedings of a Conference, June 18-21, Ithaca, NY, USA.

I have attached PDFs of the first two items.

I hope these materials are of help to you.

Sincerely,

Arturo

Thank you Dr. Rajib and Dr. Arturo for your information and appreciate your help.
