Web1 de ago. de 2024 · Synopsis Hvorslev's equation for the shear strength of clay is shown to define a surface in a space of three variables σ′, e and τ. The progressive yielding of a sample defines a loading path in this space, and the paths taken by samples in differing tests can be correlated if a boundary energy correction is applied. The final portions of all … Web15 de jun. de 2001 · ABSTRACT In the seismic analysis of pile foundations the soil is often assumed to be an elastic material and the pressure at the soil pile interface is not limited during the analysis. This may result in a considerable error, as the computed pressure from an elastic analysis may go well beyond the ultimate lateral pressure of real soil. In fact, …
