Seismic Hazard Analysis of Buried Pipeline for Design
This paper concerns mainly the following three items on seismic hazard analysis of buried pipeline for design: (1) effects of pipeline length on risk, (2) effects of local site conditions...
An Expert System for Diagnosis of Earthquake Proof for Underground Lifelines
This paper reports a fuzzy expert system for the diagnosis of earthquake proof of gas pipelines with the aid of OPS83 tool. The fuzzy theory was employed to estimate seismic risk on the...
Seismic Behavior and Vulnerability of Pipelines
In this paper criteria and related features are described pertaining to the seismic design of pipelines and pipeline systems. The presentation begins by describing the past performance...
A Methodology for Assessing the Risk of Hazardous Materials Release Following Earthquakes?A Demonstration Study for the Los Angeles Area
A methodology for estimating the risk of post-earthquake hazardous materials releases was developed for the National Science Foundation and the National Center for Earthquake Engineering...
Simplified Numerical Analysis on Earthquake Response of Irregularly Bounded Surface Layer
Evaluation of seismic response of a soft surface layer is the essence in a design of a lifeline in this layer. For this purpose, a quasi-three dimensional ground model was developed by...
Application of Lateral Spread Hazard Definition Using Liquefaction Susceptibility Index to the Design of Buried Pipelines
Recent liquefaction hazard studies have made use of relationships developed to provide direct estimates of liquefaction displacements interms of liquefaction susceptibility index (LSI)....
Gas System Repair Patterns in San Francisco Resulting from the 1989 Loma Prieta Earthquake
Leak repair calls in San Francisco were tracked immediately following the 1989 Loma Prieta earthquake. This information was subsequently obtained from PG&E and examined for possible...
The Application of a Structural Analysis Program to Floating Dock and Guide Pile Design
The floating dock systems and guide piles used in marinas are often designed using over simplified analysis techniques. However, if the dock system is flexible or if either the soil conditions...
Frictional Base Isolation Using a Layered Soil-Synthetic Liner System
The application of smooth geotextile liner materials to seismic base isolation of shallow foundations has been evaluated using laboratory testing and numerical analysis. Laboratory testing...
Seismic Hazard Analysis of Buried Pipeline for Design
This paper concerns mainly the following three items on seismic hazard analysis of buried pipeline for design: (1) effects of pipeline length on risk, (2) effects of local site conditions...

Geotechnology: An Environment of Change
Today's contaminated materials�soil and water�have been investigated and analyzed by geotechnical engineers for a long time. No other branch of engineering is better positioned,...
Seattle's Good Neighbor Policy
The West Point wastewater treatment plant in Seattle sits on a spit of land jutting into Puget Sound. Close by is Discovery Park, a haven for nature lovers, located on a bluff above the...
Landfill Liners from Top to Bottom
Since EPA began requiring geomembrane liners in 1982, liner system components have multiplied rapidly. At the same time, there has been a movement toward relatively large, sophisticated,...
Pumping Oil, Treating Soil
Oil was discovered on hilltop land in Signal Hill, Calif., in 1921, setting off one of the most wild land rushes the state has ever seen. Some 70 years and 20,000 oil wells later, the...
Excavating, OSHA-Style
When the Occupational Safety and Health Administration implemented its new, tougher trenching guidelines in July 1990, the agency opened the door for inventive excavation techniques. Contractors...
Progressive Failure Probability of Soil Slopes Containing Geologic Anomalies
The variability in the redistribution of stress during sliding failure of a slope is first studied. Presence of a geologic anomaly is shown to affect the failure path pattern and likelihood...
