| Outline of Final Research Achievements |
Creep deformation and weathering environment of sandstone blocks composing Angkor temples such as Angkor Wat, Banteay Kdei, and Ta Prohm were analyzed based on a finite-element analysis and densely thermal environmental analyses. As the result, we found that the formation of hollows developed on sandstone columns is caused by stress concentration due to dead load of the building, in addition to previously reported weathering processes. Furthermore, weathering impacts for sandstone blocks may increase, because of progressing of heating and desiccation derived from heat storage due to direct insolation. For the sake of preservation of Angkor temples it is important to reconsider thermal buffer effect of green tract of land mitigating the insolation.
