Experimental p-y curves for liquefied soils from centrifuge tests

Construction of simplified design p–y curves for liquefied soils

In practice, laterally loaded piles are most often analysed using a ‘beam-on-non-linear-Winklerfoundation’ approach, whereby the soil–structure interaction is modelled by means of p–y curves. Although well-calibrated p–y curves exist for non-liquefied soils (e.g. soft clay and sand), the profession still lacks reliable p–y curves for liquefied soils. In fact, the latter should be consistent wit...

Capillary pressure curves from centrifuge data: A semi-iterative approach

where the kernel K is known exactly and given by the underlying mathematical model. g is only known with a limited degree of accuracy in a finite and discrete set of points x1, . . . , xM . However, the sought function f (t) is continuous. By the nature of the right-hand side, g(x), equation (1) is a discrete inverse problem which is ill-posed in the sense of Hadamard [9]. By a parameterization...
