Harmonic Vertical Pile Response in Non-Homogeneous Medium
This paper describes the application of the boundary element method to determine the steady state response of vertically loaded floating piles in a non-homogeneous medium in which the...
Vibration Isolation of Structures From Surface Waves in Layered Soil
This work deals with the problem of isolation of structures from ground transmitted surface waves generated by machine foundations. The isolation is accomplished by means of rectangular...
Offshore Platforms Subjected to Wave Forces
The dynamic analyses of offshore platforms are mostly based on the lumped mass matrix method in the frequency domain. Although the approximations involved in the lumped mass matrix method...
The Assessment of Freeze-Thaw Damage in Cement Stabilised Soils
Whilst the ASTM Freeze-thaw test was not originally conceived as a means for classifying the frost resistance of cement stabilised soils it has become accepted for this purpose, with the...
Structural Monitoring Concepts for Arctic Pipelines
Terrain instabilities producing differential soil movements are the predominant features affecting the structural integrity and design of buried pipeline systems in the arctic. Current...
Continuous Loading Consolidation Testing Using a Microcomputer for Control and Data Acquisition
An overview of some of the methods of one-dimensional consolidation testing currently in use is presented, including the load-increment test, the constant rate of strain test, the constant...
A Demonstration Expert System to Aid in Assessing Groundwater Contaminating Potential by Organic Chemicals
An expert systems approach to evaluating mobility and degradation of organics in soil systems is compared to conventional programming techniques. An expert system has been developed in...
A Method for Computerized Site Characterization
Site characterization, the process of evaluating subsurface soil, rock, and groundwater conditions and their impact on project design and construction is a common element in every major...
Effectiveness of Erosion Control
Erosion control in the urban environment is addressed from the perspective of the mechanisms of erosion. The primary cause of erosion in urban areas is flowing water. Measures are identified...
Constructing a Better Environment
The civil engineer is traditionally designated the jobsite environmental engineer during construction, and is responsible for managing environmental protection and monitoring. Jobsite...
Grouting a Sand Dam
Hardy Dam, owned by Michigan's Consumers Power Co., was constructed in 1929 by dumping sand from railroad trestles for an embankment to support a concrete core wall. Some...
Soil Nailing a Wall
Soil nailing is the reinforced-earth idea (in which the earth must be backfilled behind the wall) applied to cut situations. Soil nails are an inexpensive post-tensioned tieback, consisting...
Jet Grouting: Snail's Pace of Adoption
Jet grouting is grouting of soil, but the process, the equipment and the subsurface product are different from the familiar ones. Here the cement grouting is mixed in situ with the surrounding...
Wicking Bay Muds
Mud deposits in the San Francisco Bay area make construction difficult. Subsidence prevents many from building in the area. Engineers for O'Brien Kreitzberg conquered this...
Research on Transportation Facilities in Cold Regions
Transportation facilities research in cold regions, reported in this session proceedings, begins with a field study showing that ground surface characteristics have a significant effect...
Boston's Water Resource Development
Past, Present, and Future
This volume contains five papers describing diverse aspects of water supply, water power, and wastewater disposal in eastern Massachusetts. Three papers discuss Boston's water...
Leak Detection Is Just a Piece of the Pie
This paper emphasizes that leak detection is part of the proper management techniques that must be used to control unaccounted-for water. In order to effectively understand the pieces...
Boston's Future Water Supply
The Massachusetts Water Resources Authority is responsible for planning and providing water to metropolitan Boston. Recent state legislation directs that conservation, development of local...
Ground Freezing for Construction
For almost a century, freezing has been used successfully as an art to stabilize ground and control groundwater. First employed by the mining industry in Europe, it has since been widely...
Trouble in Our Own Back Yard
One million tanks will leak toxic and hazardous substances into the U.S. soil within the next four years. Prevention begins with rapid discovery and probability analysis. Various cleanup...
