Centrifuge modeling of fault propagation through alluvial soils

Centrifuge Modeling of Fault Propagation through Alluvial Soils

Introduction. The behavior of alluvial deposits this machine is illustrated in Figure 1. It subjected to fault movements in the underlying has been employed in a number of investigations to bedrock is of major concern for critical structures date, including piles (Scott eta!., 1977; Scott, located within fault zones. An understanding of 1979), ocean floor anchors (Tagaya et al., 1977), fault pr...

Fault Rupture Propagation through Sand: Finite-Element Analysis and Validation through Centrifuge Experiments

The three notorious earthquakes of 1999 in Turkey Kocaeli and Düzce and Taiwan Chi-Chi , having offered numerous examples of surface fault rupturing underneath civil engineering structures, prompted increased interest in the subject. This paper develops a nonlinear finite-element methodology to study dip–slip “normal” and “reverse” fault rupture propagation through sand. The procedure is verifi...

Spatial Variability Analysis of Soil Physical Properties of Alluvial Soils

ited on sandy or on loamy sediments. Therefore, it is important to study not only the extent of surface spatial Analysis and interpretation of spatial variability of soils is a keyvariability, but also the distribution of subsurface and stone in site-specific farming. Soil survey maps may have up to 0.41ha inclusions of dissimilar soils within a mapping unit. The objectives deep soil horizons. ...
