Geotechnical
The intent of this study is to impose external loading conditions to test specimens that are representative of the significant deformations possible during earthquake-induced ground motions such as landsliding, fault rupture, and liquefaction-induced lateral spreading, characterizing the pipeline system capacity.
 In summer 2019, former masters student David Kyle Anderson conducted 28 tension tests on 5 different types of wire mesh used for soil stabilization at CIEST.
The main goal of this project is to investigate how the use of compacted granular columns (CGC) may help improve the seismic performance of embankments on potentially liquefiable soils.
The Sandia Senior Design Team were tasked to design a switch that activates at 9g as part of a cubesat subsystem for their senior design project.- The Los Angeles Department of Water and Power (LADWP) is currently replacing many of its open reservoirs with buried, reinforced-concrete structures to improve water quality.
This Faculty Early Career Development (CAREER) grant will create a new approach for evaluating the behavior of clusters of buildings on liquefiable ground during earthquakes and pave the way toward designing mitigation measures that improve building performance at a system level.
This project will study the seismic response of temporary and permanent cut-and-cover box structures near mid- to high-rise buildings using a combination of centrifuge testing and numerical simulations.- The Western Transportation Institue has conducted a series of modelling tests of deep patch repairing method used in Highway in our 400 g-ton centrifuge.
Shideh Dashti, assistant professor of geotechnical engineering and geomechanics at ÃÛÌÇÖ±²¥-Boulder, co-led a scientific reconnaissance team mobilized by the Geotechnical Extreme Events Reconnaissance (GEER) Association to travel to Kumamoto-shi, Japan,- Buried explosion is a complex phenomenon, involving high strain-rate soil dynamics, fluid dynamics, fractures, shocks and multi-scale physics. A comprehensive experimental program using geotechnical centrifuge modeling was conducted in conjunction with computational modeling using finite element, boundary element and discrete element and meshless methods to achieve a new level of scientific understanding of the complex multi-phase phenomena.
