On the Elasto-Plastic Behavior of an Unsaturated Silt
Due to technical difficulties related to the control and measurement of the suction in unsaturated soils, few experimental data on the mechanical behavior of those soils exits. The paper...
Elasto-Plastic Volume Change of Unsaturated Compacted Clay
Isotropic compression tests were performed on samples of unsaturated compacted kaolin in a modified triaxial cell that allowed separate control of pore water pressure and pore air pressure....
One and Three Dimensional, Three Phase Deformation in Soil
An initially saturated soil exhibits two distinct deformation patterns as it drys. First, it deforms vertically until the soil begins to drain. Secondly , it deforms laterally as well...
Flow Properties of Unsaturated Soils Under Controlled Suction
Laboratory tests were performed for the hydraulic characterization of three compacted soils under high suction. Moisture changes were studied considering some factors affecting the time...
Permeability Determination for Unsaturated Soils
A reliable approach for the determination of the soil hydraulic conductivity function relies on the parameter estimation solution approach in which heterogeneous state of saturation within...
Transit Times Through Compacted Clay Liners
Transit time, or time taken by waste liquid to move through the thickness of the liner, is a short-term performance parameter which can be used to determine the necessary liner thickness....
Performance of Horizontal and Vertical Barriers
Horizontal and vertical barriers have been used on transportation facilities to control expansive soils and minimize their damages. The effort is to minimize moisture change in the soil...
Data Base for the Design of Piers in Expansive Soils
The paper describes the parameters and the structure of the seed of a data base of properties and observed field behavior of expansive soils assembled from an extensive literature review....

Vietnam: Worth Looking Into
If it is to enter the world economy, let alone play catch-up with the booming economies of some of its neighbors, Vietnam requires massive numbers of infrastructure projects: roads, bridges,...
The Financing Fray
Interview with two executives of the U.S. firm Morrison-Knudsen: Donn Smith, senior vice president of project finance at M-K's International Group, and Richard White, vice...
Dutch Globetrotting Pays Off
The Dutch have been doing business overseas for centuries, and Dutch consultants today continue the tradition. Several Dutch consulting firms are profiled. At Fugro-McClelland, N.V., Chief...
Whose Risk Is It, Anyway?
Near the now-closed Smuggler Mine in Aspen, Colo. toxic lead sits beneath the grass of area residents' yards. A major portion of soil in the area has lead above the EPA action...
Runoff As A Resource
Recent studies have shown that storm-water flows from urban and industrial areas typically contain significant quantities of the same pollutants found in wastewater and industrial discharges....
Reclaiming Clear-Cut Land
The Savannah (Ga.) Airport Commission needed to expand the city's international airport to meet projected needs through 2007. The expansion was designed with Greiner, Inc.,...
Harry Seed, Liquefaction & the Gravel Drain
The late Professor Seed of the University of California at Berkeley established criteria for gravel drain design in a 1977 ASCE paper. Without historical proof for its viability in a real...
The Big No-Dig
As part of the Boston Harbor cleanup project, engineers will have the opportunity to make a rare, side-by-side comparison of open-cut construction and no-dig technology during the Wellesley...
