Graettinger, Andrew J.

My research interests can be broadly grouped into numerical and experimental research related to civil and geotechnical engineering. My numerical research includes work on statistical methods to quantify, direct, and conclude site exploration activities. Through reliability-based techniques I combine what is known about a site with what is most sensitive at a site to direct exploration to the most important information. This technique is also being expanded to include long-term monitoring for natural attenuation sites by identifying the most important location to monitor to assure compliance.

Employing a Geographic Information System (GIS) to solve spatial problems in civil engineering is another of my research interests. Although GIS technology has been making digital maps since the mid 80’s, only recently has the technology matured enough to be linked with civil engineering models to perform complex spatial analysis. My GIS research looks at both civil engineering applications of GIS and also advancing GIS technology to better serve civil engineers.

My experimental research in lightweight fill and waterjet drilling allows my students and I time in the laboratory to test, interpret results, and optimize designs. My lightweight fill research is looking at using recycled plastic as a replacement for polystyrene blocks that are used in some geotechnical applications. Research on miniaturizing and optimizing abrasive waterjet drilling will allow small holes (less that 5 mm in diameter) to be drilled tens of meters through any civil engineering material. These holes can then be used for direct inspection, repair, or reinforcement retrofitting.
