Circulation and Flushing in Casco Bay, Maine
A modified 3-D hydrodynamic numerical model MECCA (Model for Estuarine and Coastal Circulation Assessment; Hess, 1989) has been applied to Casco Bay, Maine, with a horizontal resolution...
Modeling Initial Mixing of Ocean Wastewater Discharges to Develop Toxic Effluent Limitations
The UM model, released by USEPA in 1992, was utilized to simulate the initial mixing of a discharge to the Atlantic Ocean near Ocean City, New Jersey. The study included field verification...
Computerized Building Settlement Analyses for a Contaminated Groundwater Remediation Project
The use of spreadsheets is becoming ever more popular in the practice of civil engineering. Engineers are able to use this tool to meet deadlines which were once insurmountable. This paper...
The Use of SCADA for Real-time Calculation and Monitoring for CT Compliance at the Ralph D. Bollman Water Treatment Plant
The contra Costa Water District (CCWD) of Concord, CA was formed in 1935 under the authority of the State Water Code. CCWD purchases its water supply from the Central Valley Project (CVP),...
Footing Load Tests on Sand
Four full size footings were load tested at a site in Texas. The embedded footings were situated on a thin layer of stiff clay underlain by a thick deposit of medium dense to dense sand....
Uplift Load-Displacement Behavior of Grillage Foundations
Full-scale field tests were conducted on steel grillage foundations for lattice transmission line towers that had been in place since 1929, 1947, and 1958. A total of eight tests were...
Analysis of the Juturnaiba Embankment Dam Built on an Organic Soft Clay
The Juturnaiba Dam, located in the northern part of Rio de Janeiro State, Brazil, has 1.2 km of its length built on an organic soft clay about four meters deep. The construction of the...
Replacement of a Failed Embankment Designed to Accommodate Large Settlement: A Case Study
Thick deposits of soft, normally to slightly preconsolidated, organic clay are common at low elevations along the riverbanks of southeast Texas. Both the moisture content and liquid limit...
A Case History of Settlement of an Embankment on Lagoonal Deposits Influenced by Artesian Conditions
A geotechnical engineering investigation was performed for the Pearl Kai Center, a shopping center in the Pearl Harbor area of the island of Oahu, Hawaii. The proposed commercial development...
Towards a Rational Method of Predicting Settlements of Spread Footings on Sand
Prediction of settlements of both large and small spread footings on sand has traditionally been carried out using methods which are largely empirical. In recent years, advances have been...
Deformation of Sand Foundations Induced by Earthquakes
This paper discusses the deformation of sand foundations during earthquakes based on the experimental results of centrifuge tests. A group of tests was conducted on two types of buildings...
Post-Cyclic Consolidation Behavior of Loose Sands
By performing Ko consolidation on samples accumulated various levels of strains and residual pore pressures due to cyclic loading, the post-earthquake settlement characteristics of two...
Prediction of Low Level Vibration Induced Settlement
A prediction model of vibration induced settlement was developed for small to intermediate vibration levels (0.25-1.78 cm/s). Seven factors affecting vibration induced settlement such...
Settlement Predictions Using Piezocone
Detailed data on settlement predictions and measured values are given for two water tanks and an area of fill constructed on a thick soft clay stratum that showed decreasing preconsolidation...
Performance of a Steel Tank Founded on a Marine Clay
For tanks on soft clays, the soil is often preloaded before tank construction to increase bearing capacity and minimize post-construction settlement. In the case history described here,...
The Influence of Engineering Judgement in the Settlement Analysis of a Test Fill Near Ch?lon-sur-Sa?ne, France
This paper describes the settlement study for a test fill near Chalon-sur-Saone (France). The soil profile at the site comprised a silty clay layer 4.2 m thick. The elevation of the ground...
Vertical Displacement Induced in Soil by Conical Shell Foundations
Shells can hold prospect for adoption in foundation engineering only if they can be projected as economical alternatives to conventional flat foundations. Therefore, the initial enthusiasm...
Consolidation Settlements and Pore Pressure Dissipation
A test fill was constructed off the coast of one of the outer islands in Hong Kong to evaluate the consolidation characteristics of a soft plastic clay deposit known as Hong Kong mud....
Settlement of Deep Compacted Fills in California
Measured settlement of deep compacted engineered fills from a single site were summarized and compared to data from other sites. The data indicate that the rate and magnitude of movement...
Compaction Grouting Stops Settlement of an Operating Water Treatment Plant
In early 1978, about a month into full-time operation, the new filter plant building for the water treatment plant for the City of Glenwood Springs, Colorado, experienced distress due...
