Design, Selection, and Application of Disc Cutters in Hard and Abrasive Rock
Disc cutters have been used on tunnel boring and shaft boring machines for many years and are a proven method to bore hard rock. This paper will study the important parameters which effect...
A High-Level Waste Repository Performance Assessment Methodology
This project was sponsored by the Electric Power Research Institute to examine methods that coordinate information from various disciplines to present an integrated perspective on the...
Visualizing the Performance of Structural Optimization Processes
Graphical constructions are discussed that enable the performance of iterative structural optimization processes to be evaluated visually. The first, a basins of attraction construction,...
A PC-CAD System for Prefabricated Steel Bridges
A microcomputer-aided analysis and design system for prefabricated steel bridges is presented in this paper. The system was customized to perform all the required engineering to analyze,...
Strategies Which Permit Multiple Discrete Section Properties per Member in 3D Frameworks
Strategies for discrete structural optimization of 3D steel frames with coupled section properties are presented. These strategies include linearized branch and bound, simulated annealing,...
Radioactive Waste: Finding a Safe Place
The Nuclear Waste Policy Act of 1981 and its amendments mandate that the U.S. Department of Energy find a repository for the nation's high-level radioactive wastes, characterize...
Getting the Lead Out
When officials from Omaha, Neb. announced an ambitious plan to revitalize an abandoned stretch of land along the Missouri River, the land itself presented one of the biggest problems....
Closing Hazardous Landfills
Designing and constructing covers for uncontrolled hazardous-waste landfills can pose some special problems�such as differential settlements as great as 50% of landfill thickness. Under...
Fear of Trying
Conventional methods for cleaning up hazardous-waste sites are expensive, subject to increasing restrictions, and don't work that well for certain types of waste. Innovative...
Building GIS Relationships Spatially and Politically
This paper advocates that the technological aspect of building a spatial GIS is not the critical factor for a successful multi-participant installation. Rather the political relationships...
Understanding Potential Legal Liabilities of Water Resource Professionals and How to Avoid Them
The salvation of the country's water resources is one of the most important problems facing it today. Focused, as they are, on a problem of such overwhelming significance,...
Siting of a Reclaimed Water Reservoir
The City of Santa Rosa (City), California, retained Woodward-Clyde Consultants to identify, evaluate, screen and rank potential sites for construction of a dam and reservoir to store reclaimed...
Forthcoming ASCE/WPCF Manual of Practice
The forthcoming ASCE/WPCF Manual of Practice for the Design and Construction of Urban Stormwater Management Systems includes, as Chapter 1, a derivation of the following text. This chapter...
Construction Contract Documents for Stormwater Facilities
This paper provides an overview of the elements of an acceptable package of contract documents for stormwater facility construction. Thoughtful an meticulous assembly of contract documents...
Pricing Policy for Water Services
Prices and pricing strategies are described in terms of their functions and revenue objectives applicable to water services. Ten pricing objectives are defined in terms of how the objective...
Texas Reservoir Projects: Permitting & Mitigation
Recent reservoir projects in Texas were reviewed on the basis of permitting and mitigation, and subsequent project costs. We document trends of increasing time to prepare and process permit...
Summary of the National ASCE Task Committee on Costs-Benefits of Various Design Frequencies for Urban Drainage Systems and Flood Control
The National ASCE Task Committee on: 'COSTS-BENEFITS OF VARIOUS DESIGN FREQUENCIES FOR URBAN DRAINAGE SYSTEMS AND FLOOD CONTROL' recommends that public officials...
Nonlinearities and Imperfections in Creep Stability
The effects of material and geometric nonlinearities and imperfections on the 'safe-load-limit' and the 'safe-service-period' of structures...
Perplexing Issues in Concrete Softening
We explore some of the proposed techniques for modeling 'softening' via the constitutive model. We seek a framework which is both theoretically sound and physically...
Computational Damage Modeling for Timber Reliability Analysis
Damage models for creep-rupture are used in conjunction with stochastic load models to evaluate lifetime failure probabilities of timber members and systems. This paper examines damage...
