Coal Mining in Alaska's Interior: Problems and Solutions
The Usibelli Coal Mine located in Healy, Alaska is currently the largest operating coal mine in the state of Alaska. The mine has recently increased production to nearly 1. 7 million tons...
Lateral Pressure in a Stiff Clay
A series of consolidated undrained and drained triaxial tests and oedometer tests were performed on horizontal and vertical specimens taken from an overconsolidated cretaceous clay. An...
Shear Mobilization on Laterally Loaded Shafts
From the results of a pressure cell instrumented rigid shaft embedded in stiff clay and subjected to horizontal static loading the side shear mobilization rate, and its contribution to...
Excavation in Hard Clays of the Keuper Formation
For the construction of a lock on the Main-Danube-Canal in South Germany a 30 m deep cut had to be excavated in the overconsolidated clays and claystones of the Keuper formation. The strength...
A Case Study of the Behavior of Seaport Facilities During the 1978 Miyagi-Ken-Oki Earthquake
This paper assesses seismic response characteristics of seaport facilities during the 1978 Miyagi-Ken-Oki earthquake by (a) compiling and assessing documented information from post-earthquake...
Landslide Dams in Japan
Damming of rivers by landslides is common in Japan because widespread unstable slopes and narrow valleys exist in conjunction with frequent hydrologic, volcanic, and seismic landslide...
Hysteretic Behavior of Composite Diaphragms
Floor systems constructed with steel-deck-reinforced concrete are described. When used to resist lateral loads these systems are referred to as diaphragms. A description of a test arrangement,...
Use of Vibration Tests to Determine Lateral Load Paths in Medium Rise Buildings
A structural system identification procedure is described in which an initial analytical model of a building is modified until it predicts accurately the mode shapes and natural frequencies...
Slab Participation in Frames under Lateral Loads
A unique opportunity to study slab participation was afforded by the U. S. -Japan Cooperative project on large scale testing. The data obtained from the full-scale 7-story building tested...
Dynamic Soil-Structure Interaction for RC Lifelines
The behavior of buried cylinders merits attention because of the impact of lifeline survivability under earthquake effects, and failures may adversely affect many communities that employ...
Dynamic Response of Highway Guardrail Post Foundations
The highway departments use two types of guardrail posts: a circular wood post and a steel W6 multiplied by 8. 5 post. The current specifications require the steel post to be placed in...
Reshaping Providence
By moving railroad tracks, river banks and several roadways, Providence, Rhode Island is reclaiming some 45 acres in its downtown and capital districts. This public works package is the...
Geotechnical Aspects of Waterfront Parks: Case Histories
This paper presents several case histories of waterfront developments, and describes the general approach that the geotechnical consultant should take in the design of these projects....
Terminal 5 Renovation?Port of Seattle
The Port of Seattle is currently renovating its Terminal 5 facility on the west bank of the Duwamish River on the west side of Harbor Island in Seattle. This paper describes the methods...
Additional Benefits from Channel Improvements
This paper describes techniques used to quantify three types of benefits resulting from enlarging the Houston Ship Channel. These benefit types are vessel casualty reduction, delay reduction...
Analytical and Empirical Methods for Predicting Channel Shoaling
Many techniques have been used in the past to predict the effects of channel enlargement on channel shoaling. These range from rule-of-thumb predictions to elaborate physical model investigations....
Overdredging at Existing Gravity Structure
Pacific Elevators Ltd. decided to upgrade Berth No. 2 to handle ships up to 70,000 DWT. The difficulty was to maintain the support of the cribs after dredging of the berth to minus 45...
Geotechnical Aspects of Stiff and Hard Clays
This publication contains articles that deal with field and laboratory measurements of engineering properties of stiff (overconsolidated) clays, and comparisons of predicted and measured...
In Situ Testing for Lock and Dam 26 Cellular Cofferdam
The in situ testing consisted of split spoon and cone penetration tests, Menard and self-boring pressuremeter tests, and Marchetti dilatometer tests. The testing program proved to be challenging...
Borehole Shear Test and Slope Stability
Three Iowa landslides analyzed on the basis of Borehole Shear Test (BST) data are reported. The soils included CL and ML loess and glacial till, and CH clay shale. Back-calculations from...
