Abstract:This paper describes the restoration project done on Angkor complex in Cambodia by JSA (Japanese Government Team for Safeguarding Angkor), which is started 1994. Especially it focuses on laterite block tower's original geotechnical structure and the current earth mound of foundation using slaked lime stabilized soil as a test result of the reconstruction project. Angkor ruins have been damaged to go to deteriorate by the geographical natural cycle of dry season and rainy season. Such environmental factor have been causing deformation and making foundation harder. Hence, the seasonal change of soil characteristics had to be taken account, and accommodated for improving mound stability even with slaked lime stabilized soil which is arranged for filing. This paper shows the soil properties of the original foundation, N-value distribution in soil layers, and the relation between additive content of slaked lime and the change in the foundation property, whose strength was our goal for the laterite block tower foundation.
