摘要

The problem of estimation of the accidents caused by explosions is one of the most critical challenges for civil engineers today. No country can ignore the accidents hazardous to environment and human. The civil engineering structures such as retaining wall backfilled with soil are the example of retaining structure and are composed of elements with different properties and distinctions. The problem active research for over 90 years due to the abundance and importance of earth retaining structures and the complexity of their dynamic response. The first steps were done by Okabe [1] and Manonobe&Matsuo [2]. In the past several decades, the Mononobe-Okabe equations have been used extensively for evaluating the magnitude of dynamic earth pressure [3, 4, 5, 6, 7, 8, 9], It should be noted that those equations were developed based on limit equilibrium for cohesionless soil and should be used only for granular soil e. g., sand. If a retaining wall cohesion soil backfill e. g., clay we should to apply result of investigated in analytical studies [10, 11, 12, 13]. There are a dimensionless cohesion term (normalized by unit weight and height of the supported soil) is employed.
