Simplified stability assessment for low volume road cut and fill slopes

O Criador:: Pratt, Randy C.
Abstract:: Many miles of roads are built in the Pacific Northwest Forests to provide access for logging and fire protection. Logging roads often cross steep mountainous terrain. Logging roads and the associated cut and fill slopes represent a discontinuity in the natural stress state in the soil mantle. These conditions result...

Prediction of low temperature cracking of asphalt concrete mixtures with thermal stress restrained specimen test results

O Criador:: Kanerva, Hannele K.
Abstract:: Low temperature cracking is attributed to tensile stresses induced in an asphalt concrete pavement that develop when the pavement is subjected to a cold temperature. Cracking results in poor ride quality and a reduction in service life of the pavement. Low temperature cracking has been predicted by regression equations, mechanistic...

Stability of gravel at artificially created spawning beds in uncontrolled streams

O Criador:: Helland-Hansen, Erik Andreas
Abstract:: Twenty-five gabion-type structures across the main stem and tributaries of the Siuslaw River in the Oregon Coastal Range, installed to expand the available spawning area for fish, were investigated for their ability to perform gravel control functions such as trapping bedload carried by the stream or holding gravel placed behind...

Biaxial bending of concrete members with applications to prestressed concrete power poles

O Criador:: Stephens, Charles Talmon
Abstract:: A method of analysis of arbitrarily shaped prestressed concrete members for biaxial bending is given. The stress-strain curve of the concrete is represented by two parabolic segments, and the effects of strain hardening of the steel are included in the analysis. An iterative numerical procedure is used to solve for...

An evaluation of coastal Oregon's marginal aggregates

O Criador:: Clemmons, Gregory H.
Abstract:: Coastal Oregon is deficient in quality construction aggregates. There is, however, an abundance of lower quality, or marginal, aggregate available for construction purposes. An evaluation of these marginal aggregates is the purpose of this paper. There are four classes of marginal rocks found on the Oregon Coast. Basalts, high in...

Application of quality function deployment in the conceptual design of a construction project

O Criador:: Hinkle, Verda O.
Abstract:: Quality Function Deployment (QFD) is a product development process that assures the needs and desires of the customer are heard and heeded during the design, development and production of a product. Though it has been used successfully in other industries, only a few companies in the U. S. Engineering and...

Nonlinear diffraction theory by an eigenfunction expansion of the Green's function

O Criador:: Chen, Min-Chu
Abstract:: A second-order nonlinear diffraction theory is developed for a large diameter circular cylinder under the action of surface gravity waves of finite amplitude in water of-finite depth. Boundary value problems are derived by using a perturbation expansion and the solutions for the diffracted waves are given in terms of Fredholm...

A large scale model study of placed stone breakwaters

O Criador:: DeBok, Donald H.
Abstract:: The results of three hydraulic model tests to evaluate the stability of a placed stone breakwater are presented and discussed. The prototype breakwater was designed to protect offshore power and port facilities in 60 feet of water and was tested at scale ratios of 1:10, 1:20, and 1:100. The armor...

Seasonal variations in tidal dynamics, water quality and sediments in the Siuslaw Estuary

O Criador:: Utt, Michael Ernest
Abstract:: Seasonal data on tides, water quality and sediments in the Siuslaw Estuary were collected. Tide and velocity data were analyzed to evaluate damping conditions in the estuary. The system was found to approximate a weakly damped standing wave. A strong relationship of damping conditions to river flow was observed. The...
