摘　　要：西安地裂缝活动主要受隐伏断裂、构造地貌、承压水头下降值及地面沉降量四大因素影响。本文根据这四个影响因素建立了地裂缝活动强度空间预测信息量模型，预测了2000年地裂缝活动强度总发展趋势。在此基础上，提出了防治地裂缝灾害的对策。The activity of Xi'an ground fissures is affected mainly by four factors,namely buried faults, geomorphic features, decline of groundwater level and amount ofground subsidence. In this paper, the spatial information model of ground fissure activity intensity was worked out according to the above four factors, and the ground fissureactivity intensity trend by the year 2000 was forecast by the model. Based on the studyresults, measures of ground fissure control and prevention was proposed.
