6th Ishihara lecture: Simplified procedure for estimating liquefaction-induced building settlement

Approaches for Estimating Liquefaction Potential of Soils

In this paper, assessment of liquefaction of soils by various approaches have been reviewed and presented in chronological order. The study focuses on procedural requirements and assessment for conventional and computational methods. Simplified method given by Seed, Tokimatsu-Yoshimi (T-Y) and Idriss & Boulanger methods of liquefaction assessmenthave been analyzed. Computational methods like ar...

Simplified model for evaluating soil liquefaction potential using CPTU

Simplified Procedures for Estimating Earthquake- Induced Deviatoric Slope Displacements

Simplified procedures are commonly employed to estimate seismic displacements of earth and waste fills. The landmark work of Makdisi and Seed (1978) has been widely adopted in practice. Although this work is widely used, it has a number of significant limitations such as decoupling the sliding block analysis from the seismic response analysis, use of a limited number of recorded earthquake moti...

Probabilistic evaluation of liquefaction-induced settlement mapping through multiscale random field models

Understanding and assessing the spatial extent of liquefaction hazard requires the spatial dependence of geotechnical properties to be taken into account. In this work, novel multiscale random field models will be developed to characterize and quantify spatial variability of geotechnical parameters across scales. Such models will then be integrated with a simplified procedure for the probabilis...

Effects of Building Construction Overburden on Liquefaction Potential of Soils

As one of the significant phenomena in earthquake geotechnical engineering, liquefaction can cause severe damages. A number of factors play a role in the occurrence of liquefaction such as magnitude of earthquake, void ratio, relative density, and fines content percentage. The impact of building construction overburdens on liquefaction is of paramount importance. The present study was aimed at ...
