Field data and Interpretation of the Results

Field Data

DMT Intermediate parameters

DMT Formulae ?? Interpreted parameters

ID contains information on soil type

KD contains information on stress history

KD correlated to OCR (clay)

KD correlated to K0 (clay)

ED contains information on deformation

M obtained from Ed using information on stress history (Kd) and soil type (Id)

Definition of M (no ambiguity)

M Comparison from DMT and from Oedometer

Cu from OCR Ladd SHANSEP 77 (SOA TOKYO)

Cu comparisons from DMT and from other tests

Interpretation of Soil Description & Unit weight

Main Applications using SDMT results

SDMT main results

SDMT repeatability

Other SDMT results

KD leads to a more economical design

Main DMT Application: Settlement prediction

Many publications & case histories of good agreement between measured and DMT-predicted

settlements / moduli:

Observed vs. predicted by DMT Silos on Danube Bank (Belgrade )

Observed vs. predicted by DMT Dormitory Building 13 storeys (Atlanta - USA)

M at Sunshine Skyway Bridge Tampa Bay ?? Florida

Possible reasons DMT good settlement predictions

Possible reasons DMT predicts well settlement

Go and MDMT on the G - ? decay curve

DMT for Compaction Control

DMT vs CPT sensitivity to Compaction

Compaction Control DMT vs CPT

Subgrade Compaction Control

Liquefaction risk assessment

SDMT for LIQUEFACTION
