8:30-8:45 am Introduction, Welcome and OverviewMarty Taube, P.E., MenardChair Ground Improvement Committee

8:45-9:45 am Evaluation and Mitigation of LiquefactionImpacts: An OverviewProf. Edward Kavazanjian, Arizona State University

Potential impacts of earthquake induced liquefaction include seismicsettlement and loss of bearing capacity of shallow foundations,settlement-induced downdrag and loss of lateral support for deepfoundations, lateral earth pressures on retaining structures, and lateralspreading and flow sliding of slopes and embankments along withassociated lateral loads on structures. Mitigation measures includedensification, enhanced drainage, reinforcement, and admixturestabilization. These impacts and mitigation techniques will be illustratedusing examples from earthquakes in the past 50 years.

9:45-10:45 am Liquefaction Lessons Learned from Recent Post-Earthquake ReconnaissanceProf. Brady R. Cox, University of Arkansas

In the past couple of years, several earthquakes ranging from magnitude6.1 – 9.0 have spawned significant soil liquefaction damage. Theseearthquakes have been studied by the NSF-funded Geotechnical ExtremeEvents Reconnaissance (GEER) association with the goal of “turningdisaster into knowledge.” This presentation provides an overview of keyliquefaction lessons learned from post-earthquake reconnaissance of theM7.0 Haiti Earthquake, the M7.1 Darfield New Zealand Earthquake, theM6.1 Christchurch New Zealand Earthquake, and the M9.0 Tohoku JapanEarthquake. Particular attention is given to the substantial economicimpact of soil liquefaction damage in New Zealand and Japan, twocountries with a history of high-quality seismic design standards. Theirstruggles with long-term recovery and rebuilding teach us that, despitesignificant progress made in recent years, considerable advances are stillneeded to effectively mitigate against costly liquefaction damage tostructures, infrastructure and lifelines.

10:45-11:15 am Coffee Break and Exhibits

11:15-12:15 pm Use of Reinforcement for Liquefaction MitigationProf. Ross Boulanger (U.C. Davis)

Ground improvement methods based on densification (e.g., vibro-compaction, deep dynamic compaction, etc.) can be highly effective inpreventing or reducing liquefaction potential but they are much lesseffective in liquefiable soils with significant fines. For soils that aredifficult to densify, ground improvement based on shear reinforcementmay be an effective mitigation method. The current state-of-the-practiceof how to account for shear reinforcement effects will be discussed.

12:15-1:15 pm Lunch Break and Exhibits

1:15-2:15 pm Liquefaction Risk Mitigation by Excess PorePressure Dissipation through Stone ColumnsProf. Russell Green, Virginia Tech

Stone columns are often used to mitigate the risk of liquefaction in loose,saturated sandy soil deposits. Commonly used procedures to determinethe minimum required spacing of stone columns for liquefactionmitigation only consider the effects of shear stress redistribution.However, increased lateral confinement, densification of the adjacentsand, and a providing a mechanism for excess pore pressure dissipationare other possible ways in which stone columns can reduce liquefactionpotential. This presentation will give an overview of a study that focusedon examining this latter benefit (i.e., liquefaction risk mitigation byexcess pore pressure dissipation through stone columns).

2:15-3:15 pm Use of Blast-Induced Liquefaction to EvaluateFoundation PerformanceProf. Kyle Rollins, Brigham Young University

Blast-induced liquefaction in conjunction with foundation testing providesa way to evaluate the performance of full-scale foundations in liquefiedsoils. This presentation will present findings from full-scale testing ofdrilled shafts, single piles and pile groups all in conjunction with blast-induced liquefaction. Lateral and axial (including downdrag) performancewill be covered.

3:15-3:45 pm Coffee Break and Exhibits

3:45-4:45 pm Lateral Spreading during LiquefactionProf. Scott Olson, University of Illinois

Lateral spread is the most pervasive consequence of seismicliquefaction. Existing methods to evaluate lateral spreadingdisplacements include empirical correlations, laboratory-basedprocedures, Newmark sliding-block approaches, and finite elementmethods; however, estimates of displacement can vary considerably. The current state-of-practice and a Newmark sliding-block approachusing liquefied shear strength ratios will be discussed.

4:45-5:15 pm Silas Nichols, Principal Bridge Engineer –Geotechnical, Federal Highway Administration

FHWA has recently issued an update to their geotechnical earthquakeengineering guidance, titled “LRFD Seismic Analysis and Design ofTransportation Geotechnical Feature and Structural Foundations.” Themanual was developed following requirements and recommendations ofthe seismic provisions in the AASHTO LRFD Bridge DesignSpecifications, AASHTO Guide Specifications for LRFD Seismic BridgeDesign, and NCHRP Report 611 entitled “Seismic Analysis and Design ofRetaining Walls, Buried Structures, Slopes, and Embankments.” Thepresentation will cover the FHWA approach to liquefaction mitigation aspresented in this manual update.

From its origins as a trading post perched on the threshold of unchartered territory, St. Louis grew to blend disparate influences – French, German, Ragtime, Rust Belt,Midwest and Southern. From the Gateway Arch designed to commemorate ThomasJefferson's vision of westward expansion, to first-rate museums, an extensivebotanical garden, and a strong musical heritage gives visitors plenty of reason to say"meet me in St. Louis."Sheraton St. Louis City Center Hotel & Suites is nestled in the downtown historic areaof St. Louis. Built in 1929, this landmark building combines modern comforts withMidwestern charm and hospitality. The hotel is steps from the Metro Link/Light Railsystem, making it simple to visit downtown and its attractions.
