ABSTRACT
Angkor Monument is not only a symbol of the traditional culture of Kingdom of Cambodia and that of the unity of the people, but also a cultural treasure of Asia. However, it is in great danger of the destruction now. So, several countries have been carrying out the restoration of Angkor Monument. In 1994, Japanese government organized JSA (Japanese Government Team for Safeguarding Angkor), led by Prof. Takeshi Nakagawa (Waseda University, Japan) and composed of specialists of various fields. From 2005, APSARA and JSA organized a joint team, JASA (JSA and APSARA Safeguarding Angkor). JSA selected Northern Library of Bayon, Prasat Suor prat, and the Northern Library inside the Outermost Enclosure of Angkor Wat as targets for the restoration, and conducted various studies and investigations about the structure of these monuments and completed re-building those two monuments. Now, JSA is planning the restoration for Bayon main tower. Our paper purposes to evaluate the risk level of the structure.
