摘　　要：为有效预防及控制建设项目突发事故,对建设项目突发事故演变的阶段性特征及其演化机理进行研究。将建设项目突发事故划分为危机潜伏期、事故爆发期、事故蔓延期和事故终结期四个阶段,归纳了各阶段的特征,进而采用尖点突变、诱因耦合和耗散结构等理论及方法建立阶段模型,阐释了建设项目突发事故演化的过程,并对事故各阶段演化机理进行了刻画。该研究有助于掌握事故发生规律,强化人们对事故演变机理的认识,便于及时采取预防和控制对策。Aiming at preventing and controlling the construction project accidents effectively, this paper makes research on revealing the characteristics and evolution mechanism of each stage of construction pro- jects accidents. The paper divides the construction projects accidents into four stages, which are latency stage, eruptive stage, spreading stage and termination stage. The paper summarizes the characteristics of each stage, and then establishes the stage model by using some theory and methods like cusp catastrophe, incentive coupling and dissipative structure, interprets the evolution process of construction project acci- dents,also describes each stage＇s evolution mechanism. The research will be beneficial for people to grasp the regular pattern of accidents and strengthen the understanding of the evolution mechanism of accidents in order to take countermeasures for accident prevention and control in time.
