Analytical method for analysis of interaction of retaining wall backfilled with soil under explosion loading
Keywords:analytical method, retaining wall, active soil pressure, explosion, dynamic analysis
Knowledge of dynamic active soil pressure behind retaining wall is very important in the design and maintenance stage of retaining wall. Dynamic load might cause permanent deformation of retaining structures and even failures with disastrous physical and economic consequences.
This paper presents the analytical method that allows calculating the displacements of backfilled soil under explosion and determining the influence to the retaining structure. The estimation method was realised with different backfill soil of active earth pressure to retaining structures under dynamic load. Results are provided in a tabular and graphical form with a comparison to the pressure at the same point of different backfill soil influences to retraining wall under the same explosion loading.
