        A numerical scheme for seismic analysis of nonhomogeneous embankment dam sections has been presented and shown to provide results that approximate reasonably well the more precise 2-D analyses in a gravel shell dam design. ...
      • 1‐D Strain in Normally Consolidated Cohesive Soils 

        Bobby O. Hardin (American Society of Civil Engineers, 1989)

      • A Laboratory Study of Blast Densification of Saturated Sand 

        Charles H. Dowding; Roman D. Hryciw (American Society of Civil Engineers, 1986)
        Laboratory tests have been conducted to investigate the potential of millisecond delays in blast‐densification of saturated cohesionless sand. A large liquefaction tank was used to prepare and contain the sand. Commercially ...
      • A Note on Bearing Capacity of Soft Clays under Embankments 

        H. S. Yu; S. W. Sloan (American Society of Civil Engineers, 1994)
        This paper presents a rigorous lower‐bound solution for the bearing capacity of soft clays under embankments. The analysis is carried out by using a numerical technique that is based on the lower‐bound theorem and finite ...
      • A Simple Question About Consolidation 

        John H. Schmertmann (American Society of Civil Engineers, 1983)
        The author poses a question about what happens to the lateral stress of a normally consolidated clay aging in an oedometer at constant vertical stress. A written and verbal survey of 32 senior engineers from research and ...
      • Active Earth Pressure Behind Retaining Walls 

        Sangchul Bang (American Society of Civil Engineers, 1985)
        A simple and realistic analytical procedure is described to estimate the eveloped lateral earth pressure behind the rigid retaining wall with cohesionless backfill soil experiencing outward tilt about the base. Included ...
      • Active Earth Pressure on Walls with Base Projection 

        Amjad F. Barghouthi (American Society of Civil Engineers, 1990)
        The effect of base projection on the active earth pressure, a classical problem in the calculation of earth pressure forces on retaining walls, is presented. Four conclusions may be drawn. The first is that the failure ...
