An analytical study for determining the post-cyclic behavior effect on shear strength of the soil has been carried out previously.  It is well known that the static and dynamic loading results in build-up of strains that are manifested as excess strength in the soils.  This paper is rooted in the past studies by many researchers in static and dynamic loading and the main purpose of this paper is to describe the presentable data and method were used in case studies to show how the cyclic loading may play a role in development of shear strength by critically examining and documenting the current state of practice.  The proposed laboratory frequencies approximately incorporate with the real or undergo dynamic cyclic loadings.  This paper are discussed the variation in strength of post-cyclic sample from peat, clay and sand in variety of several case histories are presented.  Further analyzes the stress-strain response of these samples in undrained triaxial loading.  A dynamic triaxial testing concurrently was used to investigate the soil behavior.  The results after cyclic loading may be an important parameter in determining the subsequent stress path under static and dynamic loading tests to enhance the knowledge method in designing the infrastructure and comprehensive technique.
