Opening the world’s longest, deepest rail tunnel with precise measurement

监视隧道上方的大坝

在整个施工期间，隧道上方三个人造湖的周围环境需要监视：Curnera，Nalps和St. Maria。隧道的建设很可能会影响其大坝的稳定性。该监视也是使用Leica Geosystems的工具进行的。从2000年到2015年，全自动设备对整个隧道建筑的大坝进行了监视。

“Our total stations monitored the tiniest movement of the prisms that were mounted near the dams,” says Falko Henning, Leica Geosystems product manager. “Happily, no unusual movements occurred.”

There was no major delay during the construction, and the inauguration was held on schedule.
