Treating Expansive Soils
Damage that expansive soils do to light buildings can often be prevented or mitigated by preconstruction soil treatment. Treatments of three kinds are described�reworking the soil, controlling...

Sewer-Septic Tank Hybrid Promises Savings
Until recently the only options for sewage were the septic tank/leach field or conventional sewers. In some cases a hybrid of the two, called the septic tank/effluent drain, is less costly...

Highway Accident Collision Diagrams on a Microcomputer
Collision diagrams of highway accidents are schematic exhibits that illustrate the location of each accident with respect to the highway geometric features. The types of accidents; such...

Selected Papers from the Chinese Journal of Geotechnical Engineering ?1985
This book contains English translations of 19 articles selected from the Chinese Journal of Geotechnical Engineering. Five of the papers are...

Twisting in the Wind
Wind tunnel tests are being used increasingly to test the aerodynamic stability of bridges. Many designers think these tests should be used early in the conceptual design stage, rather...

Land Application of Wastewater Sludge
Prepared by the Task Committee on Land Application of Sludge of the Committee on Water Pollution Management of the Environmental Engineering Division of ASCE. ...

Taipei Trade
The appearance of this building is remarkable�so were the cost savings. A design change form rigid shear walls to a ductile frame helped keep construction of Taipei's World...

Construction Guide Liners
Geomembrane liners for waste construction require meticulous construction, monitoring and weather watching. With much concern over the longevity of geosynthetics, many overlook the extreme...

Milan's Model Metro
A number of innovative geotechnical methods were used at the extension of the Milan, Italy, subway. Jet grouting, a technique used only a few times in the United States, was notable among...

Shake-Proof Dams
Seismic trouble spots in California and along the Pacific Coast usually get the most publicity. But many people don't realize that Wyoming, Illinois, South Carolina, Utah...

Another Geotech Import: Deep Soil Mixing
A technique called deep soil mixing (DSM), imported from Japan, has been used to stabilize an existing dam foundation. When the Bureau of Reclamation discovered that Jackson Lake Dam had...

Milwaukee's Deep Tunnels�No Clone
Tunnel boring machines are excavating nearly 19 miles of tunnels 17-32 ft in diameter as part of Milwaukee's $1.9 billion upgrade of its sanitary sewage system. Laid out to...

Planning and Designing the Powerplant at Stampede Dam
Power development at Stampede Dam was complicated due to the uncertainty about future reservoir operation and the need to design for seismic risk while attempting to minimize overall cost....

Installation and Startup of the Idaho Falls Bulb Units
The Idaho Falls Low-Head Hydroelectric Demonstration Project consists of the redevelopment of three existing power plants using identical bulb turbines and generators. This paper summarizes...

Uncertainty Analysis of Field Turbine Performance Measurements
This paper presents comprehensive uncertainty analyses of two different flow measurement methods for field tests on turbines. The 'water to wire' efficiency was...

Rim-Drive Turbine for Low Head Applications
A turbine design and testing program was undertaken with the objective of developing a standardized turbine/generator arrangement that would be well suited to the 10 to 30 foot head range....

The Sand Bar Hydroelectric Project: A Case History
The Sand Bar project's major features include a reinforced concrete intake structure; 3. 5 miles of twelve foot diameter hard rock tunnel; a reinforced concrete powerhouse...

Analyses and Field Tests for Hydraulic Transients Sultan Hydroelectric Project
Two in-line Francis units with their long discharge conduit and bypass valves present some unique problems in controlling hydraulic transients in this system. The problems were compounded...

Analysis and Testing of Transient Pressures at Camp Far West Hydroelectric Project
The objective of this paper is to present a comparative discussion of the results of theoretical analysis of transient pressures and of field tests performed on the Camp Far West Hydroelectric...

Evaluation of Liquefaction Potential of Anderson Ranch Dam
