Building Safety Appraisal of Ground Fissures Effecting Zone in Xi'an/Tian Penggang1,2，Wang Sheliang1(1 Xi'an Univ. of Arch. & Tech., Xi'an　710055, China;   2 Shanxi Institute of Technology，Hanzhong 723003, China)
Abstract:Some important factors which influence the building safety while not mentioned in the Standard of Dangerous Building Appraisal (JGJ125—99)are discussed. These factors are ground fissures distinguishing, genetic types of ground fissures, effecting zones of ground fissures, ground fissure's activity rules and seismic effect. It is useful for buildings of ground fissures zones in Shanxi, and it also provides experience for other regions suffering from ground fissures disasters.
