Nature Sides with the Hidden Flaw: Lessons Learned from Failures of Earth-Support Systems
In recent years, the demand for excavations and fills of significant height has increased due to many factors, including requirements for below-grade parking for urban buildings and the need to construct...

Dry Dams and the Dayton Flood of 1913: The Origins of Integrated Systems Engineering Concepts
This article examines the history of integrated flood protection with particular focus on the 1913 Dayton Flood....

Landslide Risk Perception: Consequences of Failure to Reconcile Contradictory Beliefs
While the basis for geotechnical safety is important, public perceptions of risk and its apparent willingness to ignore or discount hazard warnings should also be considered. Why does...

Evaluation of Vertica Retaining Wall Systems
Prepared by the Highway Innovative Technology Evaluation Center (HITEC). This report describes a HITEC evaluation designed to determine the basic capabilities...

Summary, Conclusions, and Recommendations
Civil engineers have responsibilities for the planning, design, construction, operation and maintenance of physical infrastructures. These infrastructures include all types of buildings,...

Design Considerations Common To All Permeable Pavements
Impervious cover in watersheds without controls result in increased stormwater runoff and decreased groundwater recharge in response to rainfall events. This increased runoff can be the...

Grid Pavement
Open grid pavements consist of concrete or plastic units with large surface openings filled with a permeable joint material, typically small aggregate (ASTM No. 8 or No. 89), sand, or...

Hail Concepts
Hail, the product of vigorous deep convection, requires those same conditions that are conducive to the development of thunderstorms. These conditions include water vapor, especially in...

Conversion of Units
This chapter includes tables for conversion between imperial and metric units of measurement....

Radial Flow Consolidation Testing
A radial flow consolidation cell that can be used with commercially available loading frames was developed and a series of tests were performed on samples of sedimented kaolin. Simple...

Finite Difference Analyses for Sand Drain Problems
The geotechnical literature contains a number of papers in which sand drain installations are described and field performance is compared with theoretical predictions. Some of the field...

Case Study of Offshore Pile System Reliability
This paper presents the results of research effort to evaluate the reliability of offshore pile foundation systems. It is an extension of previous work by the authors [14] dealing with...

Dynamic Analysis of Equipment Structure Systems

Data Management System and Construction Monitoring Results from Wolf Creek Dam Rehabilitation
A review of the rehabilitation of Wolf Creek Dam and the Wolf Creek Information Management System (WCIMS), a Geographic Information Systems (GIS)-based application that was developed to...

Transbay Transit Center: Innovations in Automated Monitoring
The new Transbay Transit Center will include a multimodal terminal serving 11 transit systems and future high-speed rail from San Francisco to Los Angeles/Anaheim. This is an ambitious,...

Improving Construction Quality by Seeing What's Hidden Underground
One of the challenges of deep foundation projects is the inability to see what's being built at depth. Construction is hidden below ground, in soil or rock conditions that...

A Probabilistic Approach to Karstic Foundation Variability
Karst is a landscape formed in soluble rocks caused by movement of water that has become slightly acidic. Limestone, dolomite, and gypsum are vulnerable to these influences and may be...
