摘　　要：突水属重大地质灾害 ,一直引起人们的关注。本文认为突水瞬间表现一个综合效应下的瞬时地质事件。突水前表现一个与时间有关的地质作用过程。事件与过程都受多因素的影响 ,而且工程地质作用过程和突水瞬间与岩体由弹性变形 -阻尼变形 -常速流动变形 -加速流动变形相对应。突水具有时效特征。WT5,5”BZ]By study of the mechanical characteristics of fault rocks, the authors consider that the water bursting is an instant aneous geologic event under a combined effect. The process before water bursting acts as a geological activation related to time of exploitation. The geological process and the instancy of water bursting correspond to multi factors: rockmass elastic deformation, damping deformation, steady state flow deformation, and accelerated flow deformation. So the water bursting has time effect characteristic.
