Field Measurement of Dynamic Soil Properties: Adoption of cross-hole seismic method from seismology for use in geotechnical engineering.
Holographic Interferometry: First application of holographic interferometry to investigation of basic wave propagation and surface wave propagation in region of barriers.
Response of Pile Foundations to Dynamic Loads: Full scale and model tests on both single piles and pile groups in both sand and clay.
Vibrations and ground settlement from Pile Driving: Close-in measurement of ground vibration during pile driving.
Dynamic Properties of Soils: Laboratory and field measurement of compression and shear wave velocity and shear modulus of soils at both low and high amplitudes.
Development of SASW Method: Applications of FFT to evaluate shear modulus of layered media, method known as Spectral-Analysis-of-Surface-Waves (SASW).
Cone Penetrometer & Dilatometer: Study of use of penetrometer for identification of soils, and dilatometer for determination of Ko.
Grouting of Soils for Liquefaction Mitigation: Measurement of properties of grouted soils and development of economical methods of grouting to prevent liquefaction during earthquakes.
Foam Grouting to Remediate Wastes in the Ground: Discovery and development of surfactant foam grouting techniques which cleanses 99% of NAPLS and DNAPLS from contaminated soils.
Applications of Geophysics to Geoenvironmental Engineering: Selection of geophysical techniques which can be effectively applied in environmental problems.
System Director, Development of National Geotechnical Experimentation Sites: These sites are intended to reduce the site characterization costs for in situ experimentation in geotechnical engineering and geophysics.
