Discussion of 'Active Earth Pressure on Retaining Wall for c-Φ Soil Backfill under Seismic Loading Condition' by S. K. Shukla, S. K. Gupta, and N. Sivakugan

摘要

The authors' paper is welcome because it makes up for a lack in the original method of Coulomb and renders it applicable to c'-Φ soil backfills. Such a backfill type could be studied with the method of Rankine but this does not have the versatility of Coulomb's method for analyzing thrust wedges with various geometrical shapes and subject to surcharges. Therefore, the paper is very important for geotechnical engineering practice.
