Dam Repair Monitored in Unique Way

摘要

At the Razisse dam in southwest France, a Spectra Precision Focus 35 robotic total station was used to monitor structural movements during major repairs. The Focus 35 monitored to a half-millimeter accuracy movement of the arch dam abutments during a critical six-week period in the project. Raising the height of the dam was expected to cause the abutments to settle, so the Focus 35 was positioned to measure XY movement to ensure they were settling properly and within expectations.
