Probabilistic liquefaction risk analysis including fuzzy variables

Soil Dynamics and Earthquake Engineering, 1997
Abstract A new method of probabilistic liquefaction risk analysis is developed. The variables whose effect on the process of liquefaction are known vaguely and described only through imprecise linguistic terms, are treated as fuzzy variables. The combined effect of the fuzzy variables is introduced into a basic model of transformed into a random ...

Liquefaction risk analysis for a harbor fill

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1989
Abstract Many coastal fills constructed of dredged and dumped sand are loose and may be susceptible to liquefaction. This paper describes a methodology for liquefaction risk analysis for such fills and uses Harbor Island, a hydraulic fill in San Diego Bay, as an example.

A hypothesis for mitigation of risk of liquefaction

Géotechnique, 2003
INTRODUCTION Liquefaction of sandy soils during earthquakes is a cause for concern as it may lead to disastrous consequences, such as significant structural damage and loss of life. Considerable advances have been made in recent years in the area of numerical analysis of soil liquefaction.

Spatial variation in liquefaction risk

Géotechnique, 1998
Basic concepts and methods of random field theory, useful for characterizing 'distributed disordered systems', are applied to a soil deposit to evaluate the spatial extent of liquefaction under typical conditions. The soil deposit, modelled after a site located at the Wildlife Management Area in California, is represented by a three-dimensional random

Risk Analysis for Ground Failure by Liquefaction

Journal of the Geotechnical Engineering Division, 1978
A risk analysis has been developed for studying the likelihood of earthquake-induced ground failure by liquefaction. In this analysis, a new empirical method for evaluating the liquefaction potential at a site is employed. The method is based on interpretation of case histories in terms of earthquake magnitude and hypocentral distance.

Property Risk Assessment for Liquefied Natural Gas Liquefaction Plants

Volume 9: Oil and Gas Applications; Supercritical CO2 Power Cycles; Wind Energy, 2019
Abstract Liquefied Natural Gas (LNG) liquefaction plants have become increasingly important as natural gas is exported from the United States of America to markets world-wide. Downtime of any part of the process train (gas turbine, compressors, controls, etc.) due to failure of one or more of its components can result in high costs.

Simplified Approach for Liquefaction Risk Assessment of Transportation Systems: Preliminary Outcomes

2020
In the present study, a strategy to assess liquefaction risk of road infrastructures has been proposed, as combination of liquefaction hazard, infrastructures vulnerability and exposure of transportation network. The proposed methodology includes a capacity analysis of the road network performed on both pre- and post-liquefaction scenarios to evaluate ...

Zoning for Liquefaction Risk in an Italian Coastal Area Using CPT

1999
With a view to drawing up digitised maps of liquefaction risk along the Romagna coast, for which about eight hundred cone penetration tests (CPT) are available, four different methods based on CPT to evaluate safety factor profiles are analysed and compared. The methods considered are those proposed by (1) Robertson and Wride (1997), (2) Suzuki et a!. (

Liquefaction Risk Assessment: Evaluation of Three Statistical Models

Transportation Research Record: Journal of the Transportation Research Board, 1996
One approach to liquefaction risk assessment is based on a comparison of the earthquake and soil parameters for the site under study to those known to have either caused or not caused liquefaction at other sites during earlier earthquakes. In this study, three statistical models for liquefaction risk assessment are evaluated and compared.

The Liquefaction Risk Analysis of Fine Sand Filling Subgrade

Applied Mechanics and Materials, 2011
It is signality for the Yangtse River estuary fine sand filling the highway subgrade which accounting for the lacking of filler and protecting along the line environment. Experiment results indicate that the sand has high strength, low compressibility, and good water stability.
