Pile driving produces thousands of impacts every day. Vibrations from pile driving create cracks in deep foundations for nearby structures like bridges. A team at Michigan is hoping a new sensor can predict soil settlement before an accident occurs.
Ground surface sensors have traditionally been used to measure the vibrations, but the length needed to travel from deep underground in order to reach the sensors is telling only part of the story.
Adda Athanasopoulos-Zekkos, Assistant Professor of Civil and Environmental Engineering is taking a different approach by installing both geophones and accelerometers in depth and very close to the driven pile. This has given her team data that is first of its kind and will hopefully lead to a better understanding of how much soil settlement is produced in a construction site.
