Estimation of generated earth pressure on retaining walls both in active and passive conditions forms an important area of research in civil engineering. Particularly in earthquake prone zones, it is imperative to consider the effect of earthquake in possible extreme conditions on such earth pressure so that damage or failures of retaining walls are avoided. Failure of such walls not only causes stoppage of service of the wall connected with bridge, highways or basement walls, but also causes enormous problems for mitigation of disaster due to earthquake. Several works for estimation of dynamic earth pressure on retaining walls have been presented in recent few decades. In this paper, results of proposed analytical methods to estimate the active and passive earth pressure under earthquake conditions have been presented. The methods provide direct approach to establish the probable failure surface and corresponding developed pressure in both active and passive conditions. The basic assumption for developing the method is by considering plane failure surface, and effects of earthquake have been considered in pseudo-static fashion. Some comparisons of results from the methods have also been made with results from some methods available in published literature. |
