Building Beneath Boston
Up/down construction is a method in which a project's substructure and superstructure are simultaneously built. The substructure's wall, column and foundation...

Fixing Foundations
Conventional underpinning or pilings are still the most common construction methods used to strengthen foundations, but new grouting techniques are giving engineers some fresh alternatives....

Approximate Methods of Structural Analysis: Principles and Pitfalls
In this modern age when the trend in structural engineering and structural engineering education is to make more and more use of computers and standard structural analysis programs, there...

Structural Approximations in Multi-Story Buildings
Simplified computer analyses and various approximate hand calculation methods are extremely valuable in structural engineering for multi-story buildings both during the preliminary design...

The Boundary Element Method in Engineering Practice
The boundary element method (BEM) provides an excellent basis for the development of integrated design and analysis systems. The technique possesses the advantages of simple model generation,...

Approximate Preliminary Methods for Design of Lateral Load Resisting Systems in High Rise Buildings
A new group of optimization programs uses the speed and power of modern computers to eliminate the need for guessing preliminary sizes. Starting with any arbitrary sizes and a fixed geometry,...

Verification of Approximate Methods of Structural Analysis
Sophisticated computer programs for the determination of the effects of instability on the inelastic stress resultants in steel structures will appear to be 'black boxes'...

How Can we Deal with NIMBY in Nuclear Waste Management?
The effects of the NIMBY Syndrome on the siting of nuclear waste disposal facilities are described, and its causes are examined. The failure of traditional siting approaches and communications...

Curriculum and Instruction in Nuclear Waste Disposal
Curriculum and instruction in nuclear waste disposal is part of the larger problem of curriculum and instruction in science. At a time when science and technological literacy is crucial...

Evaluation of Geoscientific Information Systems for Three-Dimensional Ground-Water Modeling, Yucca Mountain, Nevada
Fully three-dimensional representations of the geologic system at Yucca Mountain have been developed using a Geoscientific Information System, which is an expansion of a traditional Geographic...

Predicted Thermal and Stress Environments in the Vicinity of Repository Openings
An understanding of the thermal and stress environment in the vicinity of repository openings is important for preclosure performance considerations and worker health and safety considerations...

Boundary Integral Methods for Unsaturated Flow
A boundary integral equation method (BIEM) is described for numerical analysis of quasilinear steady unsaturated flow in homogeneous material. The applicability of the exponential model...

Theory of Matrix and Fracture Flow Regimes in Unsaturated, Fractured Porous Media
The flow behavior of a two-dimensional, unsaturated fracture-matrix system is characterized by a critical flux q_f^*...

Barometric Pumping of Contaminated Gases Through Fractured Permeable Media
Contaminated gases may be transported vertically through a fractured permeable medium by the breathing process which is associated with cyclical changes in the barometric pressure. A review...

Activities Aimed at Qualification of a HLW Disposal Container
A container is being developed for the permanent disposal of used fuel from CANDU nuclear reactors in a deep underground disposal vault. The container is required to isolate the fuel from...

Validation of Source-Term Models Using Natural Analogues
A comparison is made between the predicted distribution of copper calculated by the AREST source-term code and the measured profiles for copper surrounding a bronze cannon that was emplaced...

Principles of the NATM and Other Uses of the Geologic Monitoring Techniques
The NATM (New Austrian Tunneling Method) differs in several respects from other construction methods. Also referred to as the 'sequential support method' or the...

Status of WIPP Compliance with EPA 40 CFR 191, December 1990?SAND90-2424C
Sandia National Laboratories is conducting performance assessments for the United States Department of Energy to use in evaluating compliance of the Waste Isolation Pilot Plant with EPA...

Application of TQM to the Waste Management QA Regulatory Arena
Over the past several years, a number of the scientists involved with the high-level radioactive waste repository project have expressed concern regarding the application of quality assurance...

The Shaft Excavation Effect Experiment
The Shaft Excavation Effect (SEE) experiment has been carried out by Power Reactor and Nuclear Fuel Development Corporation (PNC). Corresponding to this experiment, an evaluation system...
