ABSTRACT
Underground space can be characterized as protective, quakeproof, environmentally stable and insulated from the outside, which are favorable for the exhibition and preservation of cultural relics. Compared with common architecture, underground space, completely enclosed or covered by soil, offers better protection from all kinds of natural disasters. The underground museum takes advantage of the nice insulation effect of the stratum to reduce noise index and promote the utilization of the environment. The Museum of the Yang Emperor Mausoleum of the Han Dynasty lies next to the emperor mausoleum, in the northern suburb of Xi’an. The advantages of placing some invaluable cultural relics underground are: most parts are not exposed to aboveground space; the limited entrances and exits make it easy to watch and inspect the relics, and therefore theft-proof; the powerful anti-disaster capability of underground space provides necessary safeguards when disaster occurs.
