Transmitted Swelling Pressures on Retaining Structures
The main objectives of this paper are to describe a finite element model to simulate the lateral swelling behavior of expansive soils as a function of soil suction change in the soil domain...
Aspects of the Behavior of Clays on Drying
The drying behavior of compacted London Clay mixed with varying proportions of fine sand is examined, measuring the changes of sample volume, water content and suction. Particular attention...
The Transistor Psychrometer: A New Instrument for Measuring Soil Suction
The transistor psychrometer is the latest instrument available for the measurement of soil moisture suction. It has been developed over a number of years and is very similar in operation...
Modelling the Behaviour of Compacted Soils
Predictions based on a recently developed model for unsaturated soil behaviour have been compared with some results of two experimental programs on compacted soils recently published in...
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...
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...

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...
Slip-Lining Solution
Grouting the annular space between a corroded sewer pipe and newly installed liner pipe is a stage of a typical sewer line rehabilitation project which contains hidden problems and difficulties....
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.,...
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...
Egypt's Real-Time Water Management
The challenge and complexity of efficiently managing the distribution of the 55 billion m that Egypt draws from the Nile every year has prompted the country's Ministry of...
An Example of Rubble Mound Construction Procedures
The Gold Coast of Queensland, Australia, is in an exposed coastal zone that is now suffering from major problems with both the availability of suitable large rubble armour and its durability...
Durability of Stone for Rubble Mound Breakwaters
