Dismantling for reconstitution of N1 Tower of Prasat Suor Prat, Angkor Thom, Cambodia

摘要

Prasat Suor Prat, an independent masonry tower, was dismantled before restoration workrnby JSA (Japanese Government Team for Safeguarding Angkor) to study possible mechanism that hadrncaused inclination of the towers and horizontal spreading of stair stones. Dismantling upper structures asrnwell as foundation mound were performed. Archaeological trench had revealed the mechanism of deformationrnof the structure as well as foundation. To avoid the possible defects, strengthening soil groundrnwas selected rather than adapting the same methodology of only dense compaction of sand as done inrnancient Angkor.
