Embankment Seepage Control Design and Construction
For seepage control features of embankment dams, design criteria and construction practice is reviewed as it is reflected in the experience of the U. S. Army Corps of Engineers. The generally...
Fracture and Fragmentation of Rock Materials by Explosives
Explosives are used in various commercial applications including the extraction of natural resources from the earth and removal of materials for new construction. These applications include...
Oil Shale Fracture Characterization by a New Model
Fracture toughness of oil shale is a property which is essential for fracture characterization needed for energy resource development and recovery. However, a data base for fracture toughness...
Simulation of Rock Fracture with the 3-D SHALE Code
The 3-D SHALE code simulates the propagation of stress waves and the occurrence of fracture in brittle solids. The physical models and numerical methods in this code are similar to those...
Prediction of Highway Construction Noise Levels
A model for the prediction of noise levels from highway construction operations has been developed under sponsorship of the Federal Highway Administration (FHWA). Noise sources are geometrically...
Environmental Noise Control for Industrial Facilities
The authors present a brief discussion of the criteria used to evaluate environmental noise control problems. Then, they discuss environmental noise control in the power, petroleum, gas...
Composite Bridge Design in Germany
A span length between 40 m and 12 m has been regarded as optimal up to the mid-60's for a composite design to compete with prestressed concrete or steel alternatives. With...
Dynamic-Fatigue Response of Continuous Composite Bridges
The dynamic response of continuous composite bridges and the influence of fatigue loading at resonance frequency on the structural response are investigated. It is shown that cracking...
Seminar Summary and Research Needs
All the papers presented in the technical sessions of the seminar are summarized and, in some cases, commented upon. The needed research in composite and mixed construction is described....
Rebuilding America
Infrastructure Rehabilitation
The future of the nation demands a solution to the problem of our deteriorating infrastructure. Civil engineers are called on to act as guardians of our public works facilities that must...
Modelling Complex Water Distribution Systems
A program previously used for the analysis of hundreds of water distribution systems was successfully modified to provide the features needed for the extended simulation of large complex...
Indoor Air Quality Simulations with the Mass Balance Model
Recent studies relate energy conservation measures, specifically to reduction of the air exchange rate of residences, with potential adverse health effects due to human exposure to increased...
Prototype Laser Fluorescence/Fiber Optics Groundwater Contaminant Detector
Laboratory testing of a prototype field-portable instrument for in-situ laser fluorescence analysis of groundwater contaminants using fiber optics is discussed. Gasoline, gasoline components,...
Resource Recovery Mass-Burning Incineration
The various types of incineration systems are discussed, and the technical and economic factors to be considered in developing a resource recovery project are examined....
Environmental Infrastructure: Does Civil Engineering Education Meet the Challenge?
The author explores some avenues for re-direction of the civil engineering education process to become more responsive to the needs of infrastructure re-development in the areas of water...
A Stepwise Approach to Environmental Systems Maintenance Management
This paper provides a systematic approach to establishing a maintenance management program for environmental infrastructure. It begins by discussing the definition of program objectives,...
Roller Compacted Concrete
Roller compacted concrete has emerged recently as an economical material and rapid method of construction for use in gravity dams, overflow structures and heavy duty pavements. The economics...
The Bowhead Whale and Offshore Petroleum Operations in the Arctic
Eskimos, environmentalist groups, and government agencies have stated their concerns about possible effects on the bowhead from offshore petroleum operations. These concerns fall into...
The Strategic Petroleum Reserve Ocean Monitoring Program?An Introduction to Environmental Aspects of the Engineering Design Process
A model describes how determinations can be made on the effects of an engineered work or product in the environment. The engineered work can be a new waterway, a wastewater diffuser system,...
