Nonlinear Three Dimensional Analysis of Downdrag on Pile Groups
The downdrag on pile groups was investigated by using a numerical analysis and an analytical study. The emphasis was on quantifying the reduction of downdrag on piles in a group due to...
Consolidation Characteristics of an Offshore Clay Deposit
This paper summarizes the results from a comprehensive laboratory and in situ investigation of an offshore clay deposit in the northeastern coast of Brazil. Laboratory permeability data...
Deformations About Excavations in Highly Stressed Rock
The central business district of Sydney, New South Wales (NSW), is dominated by the Hawkesbury Sandstone, a Triassic sedimentary formation. Measurements have confirmed the existence of...
Rate of Settlement of Silt Alluvium at Trojan
Settlements of 1.83 m have been observed at the switchyard of the Trojan Nuclear Power Plant over a 22-year period since 1970. Rockfill had been placed on the site, a flood plain of the...
Tree Root Induced Settlement of a Large Industrial Building Founded on Expansive Clay?A Case History
Trees planted adjacent to buildings have been known to cause significant structural distress. In this paper, a case study is presented where a large tilt-up concrete industrial building...
Damage Evaluation of Building on Piers in Expansive Clay
A number of columns in the crawl space of a pier-supported structure founded in expansive clays were damaged as a result of ground movements since the building was constructed in 1975....
Settlement of Compacted Fills Caused by Wetting
Post-construction wetting of fills can cause swell or compression, depending on soil composition and stress conditions just before wetting. The various factors affecting swell/compression...
Settlement of Peats and Organic Soils
New advances in investigation of settlement of peats and organic soils and issues related to construction over such soft ground are presented. Peats and organic soils are well known for...
Settlement Prediction for Driven Piles and Pile Groups
Various methods of settlement prediction are reviewed for single piles and pile groups, and it is demonstrated that several of the methods give similar results. It is also found that the...
Software for Settlement Analysis
The software most widely used in engineering practice as well as for general purposes consists of word processors, spreadsheets, and databases, and these are useful for settlement analysis...
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...
Stress and Settlement of Footings in Sand
In current engineering practice, the magnitude of the settlement of a footing in sand, as compared to the settlement of a different size footing in the same sand, is considered to be a...
Downdrag on Piles: Review and Recent Experimentation
A review of the literature on pile downdrag is provided, within the context of a recent full-scale study involving two pile groups driven in soft clay, subsequently surcharged by a 2.5...
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...
Reliability-Based Assessment of Corps Structures
Due to the limited amount of funding available for maintenance, rehabilitation, and replacement of aging Corps structures, the director of civil works, Headquarters, U.S. Army Corps of...
Subjective De-Biasing of Data Sets: A Bayesian Approach
In this paper, we examine the relevance of data sets (for instance, of past incidents) for risk management decisions when there are reasons to believe that all types of incidents have...
Bayes' Theorem and Quantitative Risk Assessment
This paper argues that for a quantitative risk analysis (QRA) to be useful for public and private decisionmaking, and for rallying the support necessary to implement those decisions, it...
Risk-Based Analysis for Flood Damage Reduction
The traditional approach of the U.S. Army Corps of Engineers to flood damage reduction studies is compared to risk-based analysis, a method of performing studies in which uncertainty in...
Flood Loss Assessment with Integrated Measures
In most cases, the maximum flood loss reduction can be achieved only by an optimal combination of both structural and nonstructural measures. An integrative approach that combines the...
