Spectral Shapes and Amplifications for the Loma Prieta Earthquake of October 17, 1989
The 1971 San Fernando earthquake provided engineers and seismologists with the largest number of strong motion accelerograms ever recorded for an earthquake at that time. Those records...
Continuum Modelling of Traffic Dymamics
Two new efficient higher-order continuum models are proposed to improve modelling of traffic dynamics. The new models do not require the use of an equilibrium speed-density relationship,...
Modified Asphalt Binders for Military Airfield Pavements
This report documents a laboratory-based research effort to determine the effects of asphalt modifiers and alternate binders on asphalt airfield pavements. The modified binders were tested...

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,...
Reliability-Based Design of Tunnel Support in Jointed Rock
The presence of joints in a rock mass may cause local instability of the tunnel support and its effect on safety should be included in design. Because of significant uncertainties in the...
Bayesian Updating of Axial Capacity of Single Pile
The paper outlines a Bayesian technique to update predictions of pile driving and axial pile capacity on the basis of pile driving records. The approach enables one to systematically account...
Near-Field Differential Ground Displacement
An analytical model for the development of differential ground motions in the vicinity of a vertical, strike-slip fault is presented. The model considers a uniform, kinematic source model,...
Large Monte Carlo Simulation of Duffing Equation
This effort aims to obtain some accurate statistics of the Duffing Equation subjected to white noise through Monte Carlo simulation. The results obtained can be used to check the accuracy...
Ambiguities and Inanations of Current Plastic Pipe Specifications
This paper discusses current specifications, including materials for plastic pipe as compared to other pipe specifications, including rigid pipe materials. It discusses the ambiguities...
Short-Term Versus Long-Term Pipe Ring Stiffness in the Design of Buried Plastic Sewer Pipes
It is often discussed which pipe ring stiffness should be used when designing the long-term deflection of buried plastic sewer pipes; the short-term value or the long-term value? As the...
Stress Relaxation Characteristics of the HDPE Pipe-Soil System
All piping materials and soils are subject to viscoelastic behavior such as stress relaxation and creep. The combination of soil and pipe viscoelastic properties determine the time-dependent...
Geometrical Nonlinearity in Offshore Pipelines
Pipelines are very flexible structural systems which are subjected to various boundary conditions. For instance, during the laying process, the pipes roll on the guidance tracks on the...
The Effect of Compaction on Buried Flexible Pipes
This contribution presents an analysis of the installation of flexible pipes in granular soil. The deformation of the pipe cross section is measured in field and laboratory tests. It is...
Less Bang for the Buck
Blasting rock is practical on job sites with ample space, but on construction sites in urbans or developed settings, contractors are shying away from blasting for several reasons. Noise...
Rock Mechanics Aspects of the ESF Design
Selected aspects of the ESF rock mechanics design are outlined with emphasis placed on specific requirements imposed on the design process conducted within quality assurance-controlled...
Basaltic Volcanic Episodes of the Yucca Mountain Region
The purpose of this paper is to summarize briefly the distribution and geologic characteristics of basaltic volcanism in the Yucca Mountain region during the last 10-12 Ma. This interval...
Synthesis of Studies for the Potential of Fault Rupture at the Proposed Surface Facilities, Yucca Mountain, Nevada
Published data for the Midway Valley area, the proposed site of the surface facilities of a high-level nuclear waste repository at Yucca Mountain, suggest that recognized regional faults...
Iodine Transport Through the Soil-Plant-Atmosphere Continuum
The environmental assessment of the geological disposal of Canadian nuclear fuel waste involves transport modelling of radionuclides through the biosphere. Iodine-129 is a major fission...
