Abstract
Caverns for large physics detectors as the one for the Large Hadron Collider experiments sit nearly 100 m underground and measure several tens of meters in length, width and height. The deformation of the cavern ground slab over decades has a direct influence on the relative...

63. SHORT-TERM CONTINUOUS MONITORING OF EXPERIMENTAL FLOOR ABOVE TUNNELS OF NSLS-II

Chenghao Yu

Monitoring

Oral

Along with the long-term settlement monitoring activities of NSLS-II, the truck tunnel and utility tunnel areas, which are used for the passing of equipment, pipes and cables around storage ring tunnel, showed significant changes along with time. The changing trends in several years will be shown and more than half millimeter changes can be seen in the transverse direction of truck...
