1 In-Situ 2001 - Bali In-Situ 2001 Bali A Few Closing Comments by Paul W. Mayne at Banquet

2 In-Situ 2001 - Bali In-Situ Geotechnical Tests for Soils

3 In-Situ 2001 - Bali Specialized In-Situ Tests –Lateral Stress Cone (LS-CPT) –Cone Pressuremeter (CPMT) –Vibrocone Penetrometer for Liquefaction –Self-Boring Pressuremeter (SBP) –Iowa Stepped Blade (ISB) –Borehole Shear Test (BHT) –Vision Cone (VisCPT) –Torsional Impulse Shear Device –Push-in Total Stress Cells (TSC) –Seismic Piezocone Pressuremeter (SCPMTu)

4 Research Directions - Vibrocone Electro-Vibrocone with Piezo-Actuator Driver and Dual-Element Piezocone Penetrometer

5

6 Vibrocone Test Results Vibrocone Data from Paired Soundings at Historic Liquefaction Site, Thompson Industries, Charleston, South Carolina qtqt u1u1 fsfs Constant Rate of 20 mm/s Dynamic Motion

7 In-Situ 2001 - Bali Pile Capacity from CPT Rational Methods (“Indirect”) to assess end bearing & side friction Direct Methods - Scale up measured CPT f s and q t to Pile Interface roughness effects on measured sleeve (Frost & DeJong, 2001)  Multi-Friction Sleeve Penetrometer

8 In-Situ 2001 - Bali Oh the Places You’ll Go (Dr. Seuss) “Be Glad you don’t work on the Bunglebung Bridge that they’re building across Boober Bay at Bumm Ridge”

9 In-Situ 2001 - Bali Multi-Element Pore Pressures Triple-Element Piezocone (Fugro)

10 In-Situ 2001 - Bali Multi-Friction Sleeved Penetrometer (Frost & DeJong, 2001)

11 In-Situ 2001 - Bali Multi-Friction Sleeved Penetrometer New Soil Classification Charts f s1 -f s3 f sCPT /f s4 q t /f s1* f s2 *f s3 Brown Dirt with Stones Clays or Silts or Maybe Sands Loams Begemann

12 In-Situ 2001 - Bali Multi-Tipped Cone Penetrometer q c2 q c1 q c3 New Idea from In-Situ 2001

13 In-Situ 2001 - Bali ISC’98, Atlanta

14 In-Situ 2001 - Bali Geomusic at ISC’98, Atlanta Alan Lutenegger

15 In-Situ 2001 - Bali GeoMusic Gianfranco Totani from Italy and Julio Valdes from Panama during ISC’98

16 In-Situ 2001 - Bali GeoMusic

17 In-Situ 2001 - Bali GeoMusic for CANLEX I can’t Get No Liquefaction I can’t get no No Liquefaction    World's Largest Penetrometer

18 In-Situ 2001 - Bali On that “Note”

19 In-Situ 2001 - Bali Innovative In-Situ Devices Self-Boring Pressuremeter Self-Boring Cones - (No Rods or Trucks) Cordless Cone Memocone Audio-Cone Beerless but Bearded Fahey
