Ice Forces on Bridge Piers
The force that river ice exerts on bridge piers has been studied in the field and with models in the laboratory. Ice forces are a function of the strength, thickness, failure mode and...

Lifeline Risk Analyses: The Mokelumne Aqueduct Study
Probabilistic risk analysis methods are applied to the evaluation of seismic and non-seismic vulnerability of a 25-kilometer length of a major lifeline aqueduct system. In addition to...

Quality in the CM Constructed Project
The services of the testing laboratory on construction projects have not generally been considered as part of the construction management function. If the intention of construction management...

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...

A Power Planning Model for Seismic Risk Zones
We present a model to configure a nuclear power system consisting of plants and the distribution network. In the model, we quantify seismic risk as comprehensively as possible in terms...

Microcomputer Construction Operations Simulation
This paper summarizes the current status of an ongoing research project whose objective is to collect time data from videotapes of field construction operations and use the data as input...

Assessing Biological Effects of Contaminants In Situ
This paper presents a monitoring strategy for assessing the effects of anthropogenic contaminants on aquatic organisms. This strategy takes advantage of our increased understanding of...

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...

Effectiveness of Extended Detention Ponds
Field and laboratory studies of the performance of detention facilities for the removal of selected pollutants from urban stormwater were conducted. The laboratory studies consisted of...

Techniques for Rapid Assessment of Seismic Vulnerability
Under the impetus of a growing awareness of seismic hazards, there is an increasing effort being devoted to assessing the seismic vulnerability of existing buildings. For many professionals...

Stability Under Seismic Loading
This publication includes five papers that cover the p- ? effect on seismic structures with semi-rigid connections, the effect of panel zone deformations on the structural response behavior,...

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...

Seismic Evaluation of Lifeline Systems?Case Studies
This book contains the papers presented at the technical session titled Seismic Evaluation of Lifeline Systems?Case Studies at the ASCE Fall Convention in Boston, October 27-31, 1986....

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...
