摘要
西安地裂缝受构造控制，人工抽汲地下水产生的地面沉降、承压水位变化和其它随机因素影响使其活动加剧。利用地裂缝活动及相关监测资料，运用灰色系统理论，建立了地裂缝活动多因素影响的动态模型ＧＭ（１，３）、ＧＭ（１，４），定量评价了各影响因素对地裂缝垂直活动量的贡献，为建立和完善地裂缝防治减灾系统提供科学依据。
The activity of ground fissure in Xi′an City is aggravated under the control of tectonics and the effects of ground subsidence caused by pumping the ground confined water, level variation of confined water and other random factors. Based on the full data of ground fissure activity and other relative observations, the dynamic model GM(1,3) and GM(1,4) of affecting factors of ground fissure activity are set up by using the grey system theory in the paper. It attains the goal for quantitative assessment of the contribution to the vertical subsidence of ground fissure and provides the scientific bases for establishment and improvement of the protection and reduction system of hazard caused by the ground fissure activity.
