House Handily Approves Water Resources Development Act
The House passes the Water Resources Development Act, putting pressure on the Senate to advance its water resources bill....
Review of Climate Science for Engineering Practice
Weather and climate are a factor in civil engineering design and practice. Weather is defined as the state of the atmosphere with respect to wind, temperature, cloudiness, moisture, pressure,...
Pipe Characteristics
Microtunneling pipe should meet the following general requirements: Circular shape with a flush outside surface (including at the joints); Strength sufficient to withstand both the installation...
Pipe Design
The pipes and joints, once installed, must be capable of safely withstanding, for the project design life, all in-use service loads, including those associated with the following factors:...
Performance Limits for Deepwater Pipelines
This paper highlights the differences between onshore and offshore pipeline design. It then summarizes the results of combined external pressure, tension, and bending testing on full scale...
Estimation of Consolidation Properties of Clay from Field Observations
Analyses to obtain theoretical time-settlement curves for embankments typically make use of soil properties measured in the laboratory on small disturbed samples subject to strain rates...
Behaviour of Open-Ended Pipe Piles in Sand During Installation and Loading
An experimental study was performed to investigate the physical processes which influence the axial load capacities of open-ended steel pipe piles in sand. A double-walled pipe pile was...
Pore Water Pressures in Unsaturated Soils
Unsaturated soils are three-phase systems composed of solid mineral matter, water, and air. Such soils may be formed by either natural or artificial means. Except in moist environments,...
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...
Sinkhole Investigation and Grouting: Novel Recommendations for a Pipeline Right-of-Way
In 2009, numerous sinkholes developed within and adjacent to a 400-ft-long section of high-pressure, petroleum pipeline right-of-way that crosses under a local creek in Plymouth Meeting,...
2012 Geo-Wall Competition
Highlights from the Geo-Wall Competition at the 2012 Geo-Congress. Teams from 17 universities competed to construct a model mechanically stabilized earth (MSE) retaining wall out of craft...
Strong Diagonals
Exterior Diagonal Systems that carry both gravity and lateral loads in building structures � known as exodiagonals or diagrids � are increasingly being used worldwide to provide freedom...
Offshore Technology in Civil Engineering
Hall of Fame Papers from the Early Years
Prepared by the Subcommittee on Offshore Technology Conference Support of the Coasts, Oceans, Ports, and Rivers Institute of ASCE. This series presents...
Analysis of Dynamic Laterally Loaded Pile in Clay
Deflections of laterally loaded pile groups are strongly affected by the degree of pile head fixity. If the cap provides perfect restraint against rotation, deflections are only about...
Pressure Relief
When the two basins making up a 90 acre reservoir in New York needed to be emptied and cleaned, engineers decided to use the 2,750 ft (840 m) long concrete wall dividing them as a dam....
A Paradigm Shift in Irrigation Management
In coming decades, irrigated agriculture will be called upon to produce up to two thirds of the increased food supply needed by an expanding world population. But the increasing dependence...
Leakage Control?Finding a New Resource from the Existing One
It is estimated that by the year 2005, one person in two will have an insufficient supply of one of the world's most precious elements: water. Worse still, it is predicted that this shortage...
Stability and Loads
This chapter examines stability and loads. Topics include stability and lateral load resistance during construction; effective lengths of cantilever columns; effect on stability of frame...
Control of Microorganisms in Drinking Water
Prepared by the Water Supply Engineering Technical Committee of the Infrastructure Council of the Environmental and Water Resources Institute of ASCE. ...
Deep Freeze
In engineering, overcoming a failure can sometimes be more instructive than completing a project with unqualified success. Such was the case with the collapse and repair of a force main...
