Geostatistical approach for multi-scale seismic liquefaction risk assessment

2021
<p>The Seismic Microzonation studies (SMs), promoted all over the Italian territory by the Department of Civil Protection, provide fundamental knowledge of the subsoil response in seismic conditions at the urban scale. Amplification phenomena related to lithostratigraphic and morphological characteristics, instabilities and permanent ...

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 assessment: lesson learned from a case study

Earthquake Geotechnical Engineering for Protection and Development of Environment and Constructions, 2019
A detailed and comprehensive assessment of risk is the basis to protect communities and assist decision-making towards the sustainable management of territories. For liquefaction this process implies to simultaneously investigate seismic hazard, susceptibility of the subsoil, vulnerability of structures, economic and social relevance of critical ...

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.

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.

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.

Risk Analysis of Gas Turbines for Natural Gas Liquefaction

Volume 5: Industrial and Cogeneration; Microturbines and Small Turbomachinery; Oil and Gas Applications; Wind Turbine Technology, 2010
Procurement of process plant equipment involves decisions based not only on an economic agenda but also on long term plant capability, which in turn depends on equipment reliability. As the greater global community raises environmental concerns and pushes for economic reform, a tool is evermore required for specific and critical selection of plant ...

Risk-based liquefaction potential evaluation using standard penetration tests

Canadian Geotechnical Journal, 2000
In this paper, a new approach is presented for developing a liquefaction limit state function, which defines a boundary that separates liquefaction from no-liquefaction occurrence. The new approach is developed using a database consisting of 243 field liquefaction performance cases at sites where standard penetration tests (SPT) had been conducted ...

Direct coal liquefaction safety risks: Feedstock production and transportation

Energy, 1985
Abstract We identify major factors resulting in serious injury and loss of life during coal mining and shipment necessary to supply a hypothetical 1-quad/yr direct coal liquefaction industry with feedstock and fuel. Regional siting of direct coal liquefaction processing facilities, mine type, and coal transport mode would all govern the magnitude of ...

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.
