Backfill deflection monitoring

The Yeager airport, approximately 5 km east of downtown Charleston, West Virginia, sits on a hill with steep slopes on several sides. The airport handles approximately 250,000 passengers per year. The runway’s safety overrun collapsed after heavy rains in 2015, releasing 288,000 m3 of debris downslope. After the slope failure, Schnabel Engineering installed two SAAF model ShapeArrays to monitor the slope for further movement.

Construction on the safety overrun rebuild began in spring, 2018. Schnabel Engineering along with sensemetrics installed ShapeArray into soldier piles to monitor deflection during the backfill and anchor stressing stages. The ShapeArrays were connected to sensemetrics’ Thread platform which allowed for the rapid deployment of the monitoring system and access to real-time data within hours.

“The Yeager Airport project team selected Measurand’s ShapeArray sensors to monitor short and long deformation of the retaining wall structure due to a combination of cost, sensor spacing (value of information), installation time, and automation up-time. Such value engineering and upfront cost savings were likely considered by the design and construction team when selected ShapeArray sensors over other technologies.”
