Vacuum consolidation Technology?Principles and Field Experience
Vacuum consolidation is an effective means for improvement of saturated soft soils. The soil site is covered with an airtight membrane and a vacuum is created underneath it by using a...
Vacuum-Assisted Consolidation of a Hydraulic Landfill
As part of the Pier 300 42-acre site ground modification project, a field test of vacuum-assisted preconsolidation of hydraulic fill was studied. The objective of the test was to assess...
Compressibility for Sand Under One-Dimensional Loading Condition
Empirical equations for one dimensional compression of sand do not include parameters characterizing properties of sand grains (e.g. moduli, size and shape of sand grains, and friction...
Collapse Mechanism of Compacted Clayey and Silty Sands
The mechanism of wetting-induced collapse (hydrocompression) and the influence of fines ratios on compacted sandy soils are investigated. Various ratios of clay and silt are mixed with...
Settlement of Building Foundations on Clay Soil Caused by Evapotranspiration
This paper reports on the results of a field investigation and settlement monitoring program which involves five buildings founded on shallow foundations in the sensitive clay deposits...
Settlement of Dynamically Compacted Deposits
This paper compares predicted and measured settlements of deposits that were densified by means of dynamic compaction. Settlement records are presented for sites consisting of old, midage,...
Stress-Deformation Behavior of an Embankment on Boston Blue Clay
An 11 m high I-95 embankment was thoroughly instrumented with piezometers, settlement rods and inclinometers to measure the behavior of the underlying 40 m thick deposit of Boston Blue...
Prediction of Movement in Expansive Clays
The movement of expansive soils is usually due to a change of suction near the soil surface. The properties of the soil that govern the amount and rate of movement are the suction compression...
Methods for Risk and Reliability Analysis
Recently, there has been considerable emphasis on the state of decay in the nation's infrastructure because of its importance to society's needs and industrial growth. Water distribution...
Reliability Analysis of Water Distribution Systems
The aging and deterioration of our water supply infrastructure have resulted in performance deficiencies. Limited budgets require that resources for maintenance and rehabilitation be allocated...
Water Infrastructure Risk Ranking and Filtering Method
The availability of water distribution infrastructure is critical to the sustained support and growth of society. Water infrastructure consists of systems that carry water (pipe and irrigation...
Risk Analysis: Wet Weather Flows in S.E. Michigan
Institutional aspects of risk analysis are examined in two separate activities in the state of Michigan. The state of Michigan's relative risk project, patterned after the U.S. EPA's risk...
Poorer Is Riskier: Opportunity for Change
With regard to water resources, it is appropriate to build upon two interacting themes of the late Aaron Wildavsky (1988). The first of Wildavsky's themes is the idea of resiliency. The...
Public Perceptions of Fresh Water Issues
Risk management takes place in a context of public perceptions of fresh water quality, quantity, and availability. Regardless of their consistency or inconsistency with expert opinions,...
Quantifying Flood Damage Uncertainty
The U.S. Army Corps of Engineers (Corps) has adopted a risk-based analysis procedure to analyze the effect of uncertainty on flood damages and the benefits of flood damage reduction projects....
Environment-Irrigation Trade-Offs and Risks
Allocation of scarce water resources between environmental and commercial uses is an extremely important problem in many parts of the world. A study is under way in Australia to examine...
Climate Warming and Great Lakes Management
A decision-analysis approach to determining the relevance of information on climate change for near-term Great Lakes management decisions is outlined. Simplified applications to decisions...
Coastal Eutrophication and Temperature Variation
A 3-D hydroecological model has been developed to simulate the impact of climate-change-induced daily temperature variation on coastal water quality and eutrophication. Historical daily...
Risk and Reliability of Water Resources Infrastructure and Engineering Approaches to Risk and Reliability Analysis
The paper summarizes the second session of the conference which discussed the risk and reliability of water resources infrastructure as well as engineering approaches to risk and reliability...
Risk Management Strategies for Natural, Manmade, and Technological Hazards
The paper summarizes the fourth session of the conference which discussed risk assessment approaches in bio/chemical hazards; specific studies on people's behavior and views of natural...
