Development and Evaluation of Remediation Strategies by Deformation Analysis
Deformation analysis is providing guidance for the most efficient and economical seismic remedial treatments for Mormon Island Auxiliary and Sardis dams. The computer program TARA-3FL...
Seismic Stabilization of St. Joe State Park Tailings Dams
Tailings dams constructed by the `upstream' method are known to be seismically vulnerable, but field experience indicates that their seismic stability usually improves following termination...
Seismic Rehabilitation of Echo Lake Dam
Echo Lake Dam is an existing dam raising a natural lake in the Sierra Nevada in California, along the western edge of the Tahoe Basin. The dam was an embankment built with steep, hand...
Seismic Rehabilitation of Earth Dams
The purpose of this paper is to present methods available for engineered remediation of seismically deficient earth dams (not including tailings dams), review their strengths and weaknesses,...
Liquefaction Evaluation by Seismic Potential Procedure
Empirical procedures in common use for liquefaction evaluation employ information from a variety of sources in order to evaluate whether or not a site will undergo liquefaction. The information...
Evaluation of Rehabilitation Needs for Hydraulic-Fill Dam
This paper describes the application of analytical methodologies developed for seismic stability analysis of dams in the western U.S. (particularly the Lower San Fernando Dam in Southern...
The Use of Post-Tensioned Anchorages on the Arch Portion of Stewart Mountain Dam, Arizona
Post-tensioned rock anchorages were selected by the Bureau of Reclamation (Reclamation) to stabilize Stewart Mountain Dam against potential seismic loadings. The use of such anchorages...
Seismic Stability Modification Requirements for Pineview Dam
Pineview Dam is located 8 km upstream from Ogden, Utah, and about 8 km from the Wasatch Fault Zone. Preconstruction information and construction records available at the outset of the...
Geophysical Investigations of Concealed Faults Near Yucca Mountain, Southwest Nevada
Detailed gravity and ground magnetic data collected along surveyed traverses across Midway Valley, on the eastern flank of Yucca Mountain, Nevada reveal that these methods can be used...
U.S. Nuclear Regulatory Commission Staff Technical Position on Investigations to Identify Fault Displacement Hazards and Seismic Hazards at a Geologic Repository
This paper outlines the guidance provided to the U.S. Department of Energy by the Nuclear Regulatory Commission (NRC) staff in its Staff Technical Position (STP) on appropriate investigations...
Photogeologic Reconnaissance of X-Tunnel at Little Skull Mountain
An underground structure known as X-tunnel was investigated for the viability as an underground deep based missile system that included the capability to maintain survivability following...
Field Investigation of Mining-Induced Seismicity on Local Geohydrology
Hydraulic response of the rock mass due to earthquakes is one of the concerns in the assessment of the long-term performance of a repository. Studies performed by other researchers indicated...
Detachment Faults?Regulatory Implications for the Yucca Mountain Site
Site characterization investigations at the Yucca Mountain site, Nye County, Nevada consist of a combination of scientific data collection and analyses, and compliance with regulatory...
Seismic Reflection Profiling: Essential Geophysical Data for Yucca Mountain, Nevada
Yucca Mountain, Nevada, consists of a thick sequence of ashflow tuffs and lavas fractured into intact blocks with east-dipping strata, marginal broken zones characterized by dense faulting...
Assessment and Mitigation for Endangered Vernal Pool Invertebrates
The USFWS is considering declaring five species of vernal pool invertebrates endangered. Among these are the Vernal Pool Fairy Shrimp (Branchinecta lynchi), the California Linderiella...

The San Andreas Fault System, A Multimedia Earthquake Encyclopedia
The objective of this paper is to present the current efforts underway towards the development of the first multimedia earthquake encyclopedia. This is an attempt to use the treasury of...
Computer Methods Used on Seismic Retrofit Projects
Over a relatively short period of about twenty years, personal computers (PC's) have replaced slide rules in most engineering calculations. PC's are now staple equipment in every engineering...
Civil Engineering Computer Usage Survey
A survey of the members of the Columbia Section of the American Society of Civil Engineers (ASCE) was conducted. The purpose of the survey was to determine the computer usage of practicing...
