Seismic Response of Landfills: In-situ Evaluation of Dynamic Properties of Municipal Solid Waste, Comparison to Laboratory Testing, and Impact on Numerical Analyses

Status: Active Testing
Planned for 2012-07-17 12:00 PST

The increasing amounts of municipal solid waste (MSW) generated every year are, in their majority, landfilled. Modern MSW landfills (since the 1990s) are environmentally sensitive, sophisticated facilities and are similar in size to large dams. Recen... [more]

NEES Shared-Use Request a?? SASW Measurements at Stanford University

Status: Data Review/Interpretation
Planned for 2009-08-01 09:48 CST

The purpose of this request is to acquire the use of Thumper and Y1100 P-Wave shaker in a series of Spectral-Analysis-of-Surface-Wave (SASW) surveys of the campus of Stanford University.

Collaborative USGS-NEES Earthquake Hazard Studies in the Reno-Carson C

Status: Data Review/Interpretation
Planned for 2009-06-15 00:00 CST

The US Geological Survey (USGS) proposes collaborative experiments with personnel and equipment from the NEES facility at the University of Texas at Austin. The overall goal of this experiment is to provide high-resolution images of the sediment str... [more]

High-Fidelity Site Characterization by Experimentation

Status: Active Testing
Planned for 2009-05-25 09:51 CST

The aim of this project is to develop the capability for characterizing the detailed geological structure and mechanical properties of individual sites and/or complete basins by means of integrated in-situ field testing techniques, observation of gro... [more]

High Impact EOT: Using Thumper for Geophysical Field Camp

Status: Data Review/Interpretation
Planned for 2009-05-11 15:13 CST

We propose to acquire both 2-D and 3-D P-wave and S-wave seismic images using the NEES Thumper to identify and characterize the fractures and overlying sediments related to a known geothermal system. The Thumper is ideal at this site due to the small... [more]

Deep Shear Wave Velocity Measurements in the Las Vegas Basin

Status: Data Review/Interpretation
Planned for 2008-11-14 13:42 CST

This project will utilize the NEES a??Liquidatora?? seismic vibrator and associated data acquisition equipment, as available, in Las Vegas in Fall, 2008, as it is transported to or from another project in Southern California (Jacobo Bielak, PI). It... [more]

Deep Shear Wave Velocity Measurements in the Las Vegas Basin

Status: Data Review/Interpretation
Planned for 2008-11-10 10:18 CST

This proposal is to utilize the NEES "Liquidator" seismic vibrator in Las Vegas in August, 2007, as it is transported back to its home base in Austin or otherwise redeployed from a project at Yucca Mountain, which is about 100 miles from La... [more]

Mechanisms and Implications of Time Dependent Changes in the State and

Status: Data Review/Interpretation
Planned for 2008-10-22 10:29 CST

Field test in Indiana scheduled for July, 2008.

Collaborative USGS-NEES Earthquake Hazard Studies in the New Madrid Se

Status: Data Review/Interpretation
Planned for 2008-07-31 09:49 CST

The proposed research consists of seismic reflection experiments to image the upper 1 km of the sedimentary basins underlying the New Madrid Seismic Zone, Arkansas, and the Seattle-Portland urban area. The seismic profiles would be about 10-km in l... [more]

NEESR-GC: Seismic Risk Mitigation for Ports

Status: Data Review/Interpretation
Planned for 2008-07-20 10:12 CST

The performance of prefabricated vertical drains and colloidal silica grout will be investigated via a full-scale field test using a large, mobile shaker operated by the NEES Equipment Site at the University of Texas at Austin. The field tests provid... [more]

SASW Measurements at USGS Hawaiian Strong Motion Network

Status: Data Review/Interpretation
Planned for 2008-01-07 09:56 CST

The purpose of this project is to acquire the use of Thumper in a series of Spectral-Analysis-of-Surface-Wave (SASW) surveys of 24 stations of the U.S. Geological Surveya??s Hawaiian Strong Motion Network located on the Island of Hawaii. Dr. Kenneth... [more]

Prediction of Dynamic Response of Spread Footings on Sand

Status: Data Review/Interpretation
Planned for 2007-02-22 09:00 CST

The plan is to instrument, load, and measure the dynamic response of three shallow foundations located on a thoroughly characterized site. In conjunction, class A predictions of dynamic foundation response will be made by a small group of contributor... [more]

In Situ Determination of Soil Modulus and Damping as a Function of Lev

Status: Data Review/Interpretation
Planned for 2007-02-22 09:00 CST

Field tests will be conducted to determine the response of the soil to loads with different frequencies and amplitudes well into the nonlinear range. Numerical simulations will be developed, first with the data from the small amplitude tests to calib... [more]

Collaborative Research: Using NEES as a Testbed for Studying Soil-Foun

Status: Completed [Movie]
Planned for 2007-02-22 09:00 CST

This collaborative project addresses one of the most critical needs in earthquake engineering today: improved knowledge of soil-foundation-structure-interaction (SFSI). The prototype structure selected for investigation is a continuous bridge struct... [more]
