Richart Commemorative Lectures
The geotechnical specialty known as soil dynamics has developed during the past 25 years from a minor role to a mainstream discipline. Professor F. E. Richart has played a major role in...
Accounting for Every Pipe
The Norfolk Sanitary Sewer Inventory and Appraisal System contains individual records for each of the 20,000 pipe segments in the Norfolk sewer system. The data, assembled from construction...
Simplified Design and Construction Control for Roller Compacted Concrete
This paper presents a simplified approach to the design and construction quality control of roller compacted concrete (RCC) based on research of previous projects, discussions with experienced...
Slurry Trenches for Containing Hazardous Wastes
Slurry trench technology has not advanced much during the past 10 years due to a lack in research and development, the excerbated litigious climate in the environmental protection field,...
Flowable Fly Ash: A New Cement Stabilized Backfill
Cement stabilized fly ash placed at a plastic fluid consistency is a new structural backfill material that flows into place, either above or below water, without using sophisticated construction...
Fluid/Structure Interaction During Seismic Excitation
Hydrodynamic loading and other fluid/structure interaction effects need to be considered in the design of structures which contain, surround, or are submerged in fluids when subject to...
Just a Few More Tests and We'll Be Sure
This short paper presents a practical approach to data analysis, with the intent of suggesting that simple statistical methods - when tailored to geotechnical problems - do in fact provide...
Principles of Probabilistic Characterizations of Soil Properties
Sources of uncertainties affecting characterization of soil properties in a homogeneous soil layer include inherent spatial variability, systematic test bias, random test errors, calibration...
Coefficient of Variation of In Situ Tests in Sand
For a research project on the behavior of piles in sand for the United States Geological Survey and the Federal Highway Administration, ten sites were selected where detailed load tests...
Fire Combustion Toxicity Tests�Good Idea or Not?
The smoke from burning synthetic materials in buildings is highly toxic and is a key cause of deaths in building fires. If fire codes regulate on the basis of the toxicity of smoke of...
LAX Takes Flight for the 1984 Olympics
LAX (the Los Angeles airport) had over two dozen contractors working on site to complete their $700 million improvement plan in time for the Olympics in July. They also came up with several...
Engineering Liabilities for Design of a Bridge That Failed During the San Fernando Earthquake
On February 9, 1971, the San Fernando Valley in Southern California experienced a major earthquake. Among the victims were two men who were killed when a bridge connector ramp of a newly...
Seismic Design for Highway Bridge Foundations
This paper focuses on the determination of stiffness characteristics of piles and pile groups. Both battered and vertical pile groups are considered. Recommended methods for determining...
Seismic Considerations for the Century Freeway
The Century freeway (Interstate 105), will be an 18 mile (29 km) long, six-lane facility with 2 central transit/HOV lanes, located in Los Angeles, California. The freeway alignment crosses...
Base Isolation Concepts for Seismic Bridge Retrofit
Failures in past earthquakes have indicated three major problem areas with existing bridges. The first is the vulnerability of existing rocker and roller type bearings and this is coupled...
