Vulnerability of Soil Slopes Against Seismic Damage Based on the Effect of Spatial Variability of Soil Properties on the Development of Permanent Seismic Displacements
Abstract
The
most accurate estimation of seismic slope stability is one of the most
important areas of geotechnical seismic engineering. The assumption that soil
consists of layers with some average values for soil parameters of each layer
is not a realistic representation of actual conditions. The properties of a
soil layer are not spatially invariant and the scale of changes can
significantly affect the stability analysis of slopes. It is important to
include in the analysis as many kinds of uncertainty, especially those
resulting from the properties of soil mass and influencing the seismic
stability of slopes.Stochastic methods have been introduced in order to
calculate the uncertainty and spatial variability of soil parameters. Recent
research took into account the spatial variation of parameters using the Random
Field Theory. In theory, these variables exhibit autocorrelation, a trend in
which the soil properties of a point appear to be correlated with the
properties of neighbouring soil points (Vanmarcke, 1977). This study explores the influence of spatial
variability of soil properties on the development of permanent displacements
during seismic vibration of the slopes as well as the levels of seismic damage
that can be caused. This effect is initially investigated for a fixed value of
the maximum acceleration of the excitation, and then the results are expanded
to include the effect of the seismic intensity level. The results show the
curves of vulnerability of slopes against seismic damage and constitute a
pretty useful tool for the design of slopes, taking performativity into
account.
