St. George Harbor?A Berm Breakwater Solution in Alaska's Bering Sea
The berm breakwater concept is based on the premise that locally available materials should be used in breakwater construction to the largest degree possible. By looking at failure dynamics...
Natural Stabilization of an Eroded Permafrost Site
The paper referred to in this abstract discusses the erosional processes during and after the initial failure, proposed solutions to repair and stabilize the site, and details of the performance...
Building Around a Building
Many, maybe most, construction disasters occur as the result of the failure of temporary structures. Despite the fact that temporary structures have a critical effect on the speed, safety...
Steel Boxes Carry Rail Lines
Steel box girders plus novel bearing details led to beautiful curved bridges carrying Chicago Transit Authority trains into its Howard Yard. During preliminary design three alternative...
California's Fourteen Years of Coastal Zone Management
California's Coastal Zone Management Program has been considered the flagship of the nation; yet large questions remain as to whether the program can protect California's...
Hazardous Waste Landfill Cap System Stability
Pursuant to the regulatory requirements for control of rainfall infiltration into a hazardous waste landfill, a cap design that is impervious plus stable is required. The intent of a cap...
Temporary Structures in Construction Operations
Temporary works have a primary influence on the quality, safety, speed and profitability of all construction projects. They provide access, support and protection of a facility under construction....
Infrastructure
Repairs and Inspection
Rehabilitation of a structure in general requires considerations of unique methods of inspection and repair. Since the structures have to remain in service while the repairs are done,...
The Mexico Earthquakes?1985
Factors Involved and Lessons Learned
This publication reports initial results of study of the 1985 Mexico earthquake, one year after the event. The findings present sufficient depth of analysis to provide an understanding...
Building Over the Golden Gate
Charles Seim discusses the struggles of the original bridge advocates to garner support for the Golden Gate Bridge, an idea which originally met with a considerable amount of public opposition....
Golden Gate Bridge Improvements
The Golden Gate Bridge, Highway and Transportation District engineer talks about improvements made to the Golden Gate Bridge since opening day. Improvements covered include: wind bracing,...
Historic Bridges: Conflict Ahead
The engineer who deals with historic bridges becomes the focus of controversy in the course of determining the existing condition, predicting remaining useful life, and designing the repair...
Water Jets: Concrete Yes, Tunneling Maybe
High pressure water jets are demolishing concrete from bridge and parking decks, faster and at lower cost than by traditional means. The technique is fast becoming an acceptable option....
Investigating Failure
Failure investigations can be adversarial or cooperative, but impartiality, good engineering ethics, and professional responsibility require that the investigator begin with no premature...
Predicting Equipment Failure
At Cleveland's Westerly Water Pollution Control Center, the physical/chemical plant for treating wastewater is one of the largest of its kind, with 50 mgd average capacity....
Automating Bridge Design
To avoid some of the pitfalls of manual design calculations, Parsons Brinckerhoff Quade & Douglas engineers designing a series of bridges for a $280 million section of the New...
Aids for the Hazard Classification of Small Dams
The last few years have seen a large growth in the tools available to the engineer to better determine the risk of failure in earth dams. One of the models developed is the National Weather...
Verification of a Generalized Mudflow Model
This paper presents the results from recently completed studies verifying the accuracy and applicability of a generalized one-dimensional model for dynamic routing of mudflows. Numerical...
Management of Water Distribution System Components
The purpose of this study is to 1) analyze main break failures and 2) incorporate other drinking water distribution system components into a data base management structure for reliability...
Analysis of Scour Problems at Louisiana Bridges
An ongoing project to automate the monitoring of scour measurements at Louisiana bridge sites is discussed. The data at selected bridges is digitized and put into computer files for analysis....
