Simulations of Gravity-Driven Channel Flows of Disks Floating on the Flowing Viscous Fluid
A two-dimensional discrete element model has been applied to the problem of gravity-driven channel flow of uniform disks. The particles are floating on the surface of the flowing fluid...
Simulation of the Quasi-Static Deformation of 2D Assemblages of Rigid Discs
Although the importance of dilatancy in the constitutive behaviour of granular materials has been recognized for some time, conclusions about its evolution and dependence on different...
Numerical Simulation of Localization in Granular Materials
The structure of persistent shear bands in granular materials is investigated by numerically simulating an idealized assembly of two-dimensional particles. Flexible stress-controlled boundaries...
Interparticle Sliding and Rolling
Numerical experiments are done with a continuum plasticity program in order to study the initiation and evolution of shear bands. Many elements are used in order to resolve families of...
Pipeline Crossings
This proceedings of the Pipeline Crossings Conference, held on March 25-27, 1991 in Denver, Colorado, presents information on aspects of various pipeline crossings. It covers such broad...

The
Inspection Goes High Tech
Many believe that rehabilitation of the existing infrastructure�not net construction�will dominate the 1990s. Therefore, accurate condition assessment is crucial, since public works agencies...
Hurricane Retrofit
Houston's Sheraton Hotel and Convention Center has been retrofitted to protect it from panel pop-out (separation from building curtain walls) and curtain-wall separation from...
Computer-Monitored Grouting
With grouting operations going on at many locations around the clock on a typical large dam-foundation project, how do you make sure that the designed mix is always being used and as-built...
State Legislative Concerns Relative to Federal Hazardous Materials Transportation Regulation
States have increasingly asserted their authority to regulate hazardous materials transportation, in the face of inadequate and declining federal efforts. Areas of state interest include...
Dangerous Goods Emergency Response?The Western Australian Experience
A general overview of the State of Western Australia including: the legal framework of the Dangerous Goods and Emergency response management scenarios; particular problems unique to the...
Developing High-Risk Scenarios and Countermeasure Ideas for Mitigation of Hazardous Materials Incidents
Kansas State University (KSU) conducted a comprehensive study of the development of a set of prioritized, extreme-risk scenarios, the development of a set of feasible, practical and implementable...
Hazardous Materials Data: A Federal Perspective
This paper discusses the evolution and current status of the Hazardous Materials Incident Report System (HMIRS) maintained by the Research and Special Programs Administration (RSPA) of...
Issues in Developing Arizona's Hazmat Incident Reporting Program
The Arizona Division of Emergency Services (ADES), in cooperation with Arizona State University (ASU) - Center for Advanced Research in Transportation, and the Arizona Department of Transportation...
Managing Risks of Hazardous Materials Transportation in Santa Barbara County
This paper presents some potential building blocks which local jurisdictions can pursue to manage the risks associated with hazardous materials transportation (HMT). The recent experience...
StateGEN/StateNET and DOT Guidelines: Tools for Highway Routing of Hazardous Materials
Under the sponsorship of the U.S. Department of Energy Office, of Defense Programs, Sandia National Laboratories' Transportation Technology Center has developed computerized...
Are We Ready to Face the Geotechnical Challenges of the 21st Century?
The geotechnical engineering profession faces a bright future as many of the issues of interest to society today relate in some form to knowledge of earth sciences. Hazardous waste, environmental...
Statistical Evaluation of CPT and DMT Measurements at the Heber Road Site
A series of field tests were conducted at several sites in the Imperial Valley, South California from 1983 to 1985. The field testing program included cone penetration, dilatometer, standard...
Hypermedia and its Application to Geotechnical Databases
The concept of hypermedia has the potential for greatly enhancing existing database management software. In the present paper the concept of hypermedia is briefly described, the nature...
Geotechnical Database Management Systems for Boston's Central Artery/Harbor Tunnel Project
