Real Time Monitoring of Infrastructure Using TDR Technology: Case Histories
Time Domain Reflectometry (TDR) is a versatile technology amenable to a variety of measurements and nondestructive monitoring of infrastructure conditions. It can be utilized to monitor deformation of soil/rock and structures, monitor changes in fluid levels, and monitor water content of soils. Furthermore, this monitoring can be automated using systems...

Real Time Monitoring of Infrastructure of Subsidence Along I-70 in Washington, PA
Two longwall coalmine panels were mined at a depth of approximately 156 m (510 ft) beneath I-70 east of Washington, Pennsylvania such that it crossed the width of one panel at two locations. The Pennsylvania Department of Transportation (PennDoT) assumed responsibility for real time monitoring of both ground deformation and...

Comparison of Environmental and Blast Response in Blanford, Indiana
Mining near the town of Blanford, Indiana for a number of years has led to an opportunity for Peabody Coal Company to study and compare environmental and blast effects. Such a comparison allows description of any blast effects relative to those caused by common environmental changes, which should be familiar...

Measure the Crack Instead of Construction Vibration
Construction is omnipresent in modern-day America. It's the sound and vibration of a nation scrambling to keep up with its burgeoning population. In most states, allowable construction-induced ground motions range from 0.5 to 1.0 inches per second (in/sec) and under certain conditions up to 2.0 in/sec. However, ground motion as...

Florida SR-66 Sinkhole Monitoring
In early 2001, a sinkhole formed directly under State Road 66 near the city of Sebring in Highlands County, Florida. The Florida DOT built a land bridge over the sinkhole and the road was reopened to traffic. Since SR-66 is an important regional trucking route, it was decided that the...
