Piezo Film Technology and Applications in Geotechnical Testing

Piezo films are thin, piezoelectric membranes that can be used both as source or as receiver. They may be adapted to a variety of in situ and laboratory geotechnical testing needs. This paper summarizes fundamental concepts in piezo film technology and the physical properties of this material. The principles behind common utilizations are reviewed, and three geotechnical applications are ...

Random fields in SVSlope and SVFlux

Geotechnical engineering, as a general practice, has always struggled with quantifying the significant amount of variability that can be present at any given site. There may be variability present in field sampling methods, equipment, lab testing procedures, level of training of field personnel, or many other such factors. One particular problematic aspect of slope stability analysis is the ...

Comparing nonreinforced and internally reinforced GCL

Water is one of the most destructive forces on the planet, eroding everything from continents to human-made wonders. Water is also a vector by which contaminants spread from landfills and other waste reservoirs. Therefore, creating effective water seals has been a top concern in construction. For many years, factory-fabricated clay products have been the barrier of choice against water and other ...
