Ā°Effects of Stone Deterioration and Damage
The Northern Library of Angkor Wat (refer to p.1) is riddled with various degrees of stone deterioration and damage, a condition that is prevalent throughout the entire Angkor Wat complex. Displacements of parts of the building and the insufficient strength of the stone blocks themselves have direct bearing on the damage of element units, and this leads to the partial collapse of the building. Furthermore, the deterioration of stone blocks as seen in the weathering of their surfaces is steadily progress towards the complete loss of precious stone sculptures which have great artistic value. To ascertain the cause of these deterioration and damage and to take appropriate restorative measures,
JSA is actively conducting academic investigations from the perspectives of many different fields.
Ā°Partial Dismantling and Reassembling to Return the Scattered Stones to the Original Position
The displacement of the upper structure of the Northern Library of Angkor Wat is measured regularly. These measurements suggest the possibility of a sudden shift occurring to the monument, but they also seem to indicate long-term stability. Yet, displacements that have accumulated over years since the building was initially built cannot be ignored. When re-stacking upper elements that were missing but identified the original position, the problem lay in how to raise the stability of the building to a sufficient level. Presently, JSA is dismantling a portion of the building required at the minimum to reinstate identified elements and creating a new adjustment layer as a way to
re-stack the elements in their relative positional relationships of the original masonry.
