Relationships between Shear Wave Velocity and Depth of Overburden
Relationships between in-situ shear wave velocity and depth of overburden have been derived for various Quaternary age soils encountered primarily in Southern California. The geotechnical...

Arctic Foundation Selection: A Decision Matrix
An idealized matrix diagram is presented of the decision making process involved in determing an economic Arctic foundation type that is best suited to the proposed above-grade structure....

Standards for Pile Load Tests in Permafrost
A requirement exists to establish standard procedures for conducting pile load tests in permanently frozen soils. The methods outlined in the ASTM Standards for piles in thawed soils do...

Attenuating Creep of Piles in Frozen Soils
Results of several long-term creep tests of piles in frozen soils are analyzed; the primary or attenuating creep is predominant in most cases. For effective design of pile foundations...

Creep of a Strip Footing on Ice-Rich Permafrost
Creep settlement tests were performed on a strip footing founded on the surface of ice-rich aeolian silt permafrost. The tests consisted of applying four step loadings to a 10 in. (25....

Installation of Category I Caissons
Founding a proposed safety-related Category I structure of a nuclear power plant on rock socketed caissons necessitated using precision installation techniques. These techniques were chosen...

Case Histories: Evaluation of Drilled Pier Integrity by the Stress Wave Propagation Method
The Stress Wave Propagation Method (SWPM) was used to nondestructively investigate the integrity of straight-shaft drilled pier foundations at two sites in the Denver, Colorado area. Drilled...

Predicted and Measured Performance of a Foundation
The predicted and measured short term foundation behavior of a 28 story building in downtown San Antonio, Texas is reported. The soil is a stiff to hard clay and clay shale. The design...

Geotechnical Behavior of Underreams in Pleistocene Clay
Enlarged bases are often constructed in cylindrical drilled-and-cast-in-situ foundation elements (footings, bored piles) to increase their capacity. Enlarged bases that are cut mechanically...

Behavior of Drilled Piers in Layered Soils on Texas Barrier Islands
Twenty-eight full scale load tests and the results of 41 geotechnical studies were analyzed to correlate shear strength interpreted from field and laboratory test data with those derived...

Comparison of Caisson Load Tests on Chicago Hardpan
The results from two relatively recent instrumented caisson load tests from different sites on Chicago Hardpan are compared with a 'classic' large scale caisson...

Observations on Load Tests for Drilled Shafts
This paper focuses on three specific areas pertaining to load tests for drilled shafts: 1) basic considerations and load testing procedures, 2) interpretation of uplift load test information,...

Cover Allocation in Rangeland Watershed Management (A Review)
The importance of cover on rangelands has been recognized for many years. This paper reviews the importance of cover in terms of infiltration and erosion and provides management recommendations...

An Annual Water Balance for a Surface Mining Overburden Waste Embankment
The embankment contained a volume of 257 thousand cubic yards and resulted from a phosphate surface mining operation in southeastern Idaho. The elevation of the embankment is about 7500...

Landslide Hazard Rating for the Oregon Coast Range
The landslide hazard rating system for shallow soils on steep terrain over hard sandstone has three components: ground water response to precipitation, soil shear strength (including root...

Soil Movement and Surface Roughness on Wyoming Rangelands
Soil movement and surface roughness parameters were evaluated as a function of response to livestock grazing and semiarid shrub control treatments. Repeated elevation measurements of erosion...

Erosion, Productivity and Rangeland Watershed Planning
The Bureau of Land Management is responsible for the management of over 160 million acres of rangeland in the western United States. The principal uses of these rangelands are the grazing...

A Methodology of Assessing Nonpoint Source Pollution from Agricultural Watersheds
Appraisals of water quality impacts induced by applying watershed management practices are difficult due to many factors. Lack of existing research data base, the diffusive characteristics...

Snow Management Practices for Increasing Soil Water Reserves in Frozen Prairie Soils
It is demonstrated that stubble management practices can be used to increase snowcover accumulations in the Canadian Prairies. However, the potential for significant increasing soil water...

Interrelating Infiltration Measurements
Field measurements of infiltration rates are frequently used to index environmental conditions, soil hydrology, and the potential for rainstorm response. However, the variety of methods...
