1. PROJECT OVERVIEW AND UPDATE: NEESR-SG RESEARCH ON PILES SUBJECTED TO LATERAL SPREADING Ricardo Dobry Kickoff Meeting RPI, Nov. 19, 2005

2. Centrifuge Tests Using Pore Fluids of Different Viscosities Gonzalez (2004)

3. Centrifuge Tests Using Pore Fluids of Different Viscosities Gonzalez (2004)

4. Excess Pore Pressures Near Piles at 1-2 m Depth, Centrifuge and 1g Tests

5. Maximum Bending Moment Profiles in Single Pile Tests: 1g Test (Water) and Centrifuge Tests (Water and Viscous Fluid) Ubilla (2004)

6. Objectives of Proposed 4-Year Research Understand phenomenon of sand- liquefaction & lateral spreading in vicinity of piles Solve questions on how to design piles against lateral spreading: –Simplified (p-y) –Sophisticated (analytical platform) Clarify scaling laws, centrifuge use

7. Originally Proposed Research Tools 1g tests at U. Buffalo-NEES Centrifuge tests at RPI-NEES One test at Miki Table in Japan Advanced sensors DEM numerical experiments at RPI and Tulane U. FEM numerical simulations & development analytical platform at UCSD Advanced analytical framework at RPI

8. Originally Proposed Six 1g Tests to be Conducted at Buffalo-NEES Site (Task 1)

9. Originally Proposed Timeline and Integration of Tasks

10. Other Proposed Activities in 4-year Project Periodic project meetings External Advisory Board Interactive Web site Publication Mid-Project report of data and interpretations in 12/07 2-day Workshop in 5/08 with 30 US and international (especially Japanese) participants to discuss research and plan Year 4 Education and outreach activities Final project report and educational modules at end of Year 4 (2009)

11. Changes in Scope submitted to NSF (3 instead of 4 years, reduced budget) 1g Tests: number reduced from 6 to 4 Centrifuge Tests: number reduced from 15-20 to 10-15 Test at Miki Table: deleted DEM and FEM simulations: less 1g and centrifuge tests simulated Advanced analytical framework: scope reduced, development to start in Year 1 instead of Year 2 2-day Workshop: date advanced (summer or fall 2007?)

12. Important Recent Developments Updated List of 1g Tests Scheduled at Buffalo in 2006 in 6.2 m laminar box: –Test LG-1 (May 06): level ground, no piles –Test SG-1 (July 06): sloping ground, no piles –Test 1A (Aug. 06): sloping ground, stiff pile –Test 1B (Oct. 06): sloping ground, flex. pile Incorporation of Claudia Medina to team (to be hired as Post Doc for Task 6 in Sept. 06) Coordination with Hassan Radwan of RPI-NEES (and Jason Hanley at Buffalo-NEES) to get metadata & data viewer software ready by March 06 (basic form of advanced analytical framework) Coordination with Inthuorn Sasanakul, Operations Manager of RPI-NEES

13. Dobry’s Proposed (and necessarily very demanding) Schedule around two 1g free-field tests in 2006 March 06: –H. Radwan finishes basic form of Advanced Analytical Framework and makes it available for use to everybody. From there on, all experimental and analytical results entered through this Framework April 06: –DEM and FEM Class A predictions of Test LG-1 May 06: –Centrifuge simulation of Test LG-1 performed –1g Test LG-1 performed June 06: –DEM and FEM Class A/B predictions of Test LG-1 –DEM and FEM Class A predictions of Test SG-1 July 06: –Centrifuge simulation of Test SG-1 performed –1g Test SG-1 performed Aug. 06: –DEM and FEM Class A/B predictions of Test SG-1 –DEM and FEM Class D predictions of Test LG-1 Oct. 06: –DEM and FEM Class D predictions of Test SG-1
