Subsurface Investigations: In-Situ Geotechnical Tests

This course, based on a FHWA technical publication, covers various In-situ soil tests and procedures including standard penetration (SPT), cone penetration test (CPT), piezocone (CPTu), flat dilatometer (DMT), pressuremeter (PMT), and vane shear (VST). Also discussed are pressuremeter tests such as the Prebored (Menard) type, Self-boring pressuremeter (SBP), Push-in pressuremeter (PIP), Full-displacement type (FDP). Also, several kinds of geophysical tests that can be used for stratigraphic profiling and delineation of subsurface geometries. These include the measurement of mechanical waves (seismic refraction surveys, crosshole, downhole, and spectral analysis of surface wave tests), as well as electromagnetic techniques (resistivity, EM, magnetometer, and radar).

Topics: Standard Penetration Test Cone Penetration Test Piezocone Pentration Test Vane Shear Test Flat Plate Dilatometer Test Pressuremeter Test Specialized Probes and In-Situ Tests Geophysical Methods Geophysical Mechanical Wave Techniques Seismic Refraction Crosshole Tests Downhole Tests Spectral Analysis of Surface Waves Electromagnetic Wave Methods Ground Penetrating Radar.

Intended Audience: This course is intended for Geotechnical, Civil, Construction, Hydraulic, Structural, Foundations, and other engineers whose job description may require an intermediate knowledge of in-situ soil testing methods and procedures.
