  2. Agenda – 6/27/06 • Review of Minutes (ST, RD) • Schedule (Updated 05/2006) – No Change • UB Progress (ST) • Equipment Setup (NE, MP) • Sand Construction & Density Control (NE) • Updated Instrumentation & Coordination (NE, ST, TA) • Non-Destructive Shaking (MP, MZ, AE) • Sloping Ground – Ground Motion (MG, AE) • Decision - Pile size, thickness, etc. (July 06)

  3. Base Floor Plate Assembly - Leveling

  4. Dynamic Actuators & Reaction Beam

  5. Shaking Base & Laminar Box (add Picture)

  6. Agenda – 6/27/06 • Review of Minutes (ST, RD) • Schedule (Updated 05/2006) – No Change • UB Progress (ST) • Equipment Setup (NE, MP) • Sand Construction & Density Control (NE) • Updated Instrumentation & Coordination (NE, ST, TA) • Non-Destructive Shaking (MP, MZ, AE) • Sloping Ground – Ground Motion (MG, AE) • Decision - Pile size, thickness, etc. (July 06)

  7. Hydraulic Filling Trials & Density Controls Slurry Pump (5 HP, 3f, 208V, 14.5 A) Sand Slurry Water Ottawa F-55 Sand Water Container-B Circulating Water Pump Container-A

  8. Sand Construction– Outdoor Hydraulic Filling Trials • Simulate Pumping into Laminar box • Control Pumping Rates • Control Discharge Water Depth & Nozzle • Density Tests • Pipe full length (250ft) • Raised to the height of Laminar box

  9. Hydraulic Filling Trail – June 15, 06 • Water depth= 2 – 4 ft, • Discharge Pipe horizontally moving • Nozzle swinging

  10. Hydraulic Filling Trial – June 21, 06 • Water depth= 1 – 2 ft • Horizontally moving • Vertical nozzle

  11. Density Control Tests Bucket Density ( 6 to 9 Buckets for every 3 ft lift) Cone Density

  12. Density Data Better Control Possible in the Lab.

  13. Hydraulic Fill – Field Data(Mitchell et al.)

  14. Conclusion • Hydraulic pumping into Laminar box feasible • Density depends on pumping rate, water depth, discharge nozzle angle. • Low Dr (15%) at large water depth • High Dr (80%) at low water depth • Variability can be controlled • Bucket Density method works well & easier to implement • Further outdoor trials planned (July 1st/2nd week) • Laminar Box Filling Trials – Planned week 4/July

  15. LAB Reaction Wall Diffuser Slurry Pump (5 HP, 3f, 208V, 14.5 A) Laminar Box (LB) 3”/ 350 ft Hose Water Sand Slurry Ottawa F-55 Sand (150 T) Water Strong Floor Circulating Water Pump Sand Container Sand Preparation (Test LG-1) – July week 3/4 Placement rate / Density – To be worked out ~ 30% - 50% Feasible Sand Hydraulic Placement - Schematic Diagram
