Based On The Theory Of Complex System Brittleness Construction Safety Accident Control Research

The happening of the safety accident is complex dynamic process, the reasons ofthe system collapse is the result of the interaction of its factors.So if want to reveal theroot casuse, we need to establish the construction safety accidents system model,andanalyse the elements in the model in order to satisfy the need of the accidentmanagement. From the point of view of the complex system brittle,the breakdown ofthe factors result in the collapse of the other elements that have a brittle contact withthem in the system, in this series of the brittle spread,finally the top events of the brittlesystem come to happen.The paper do a brittle analysis for the construction safety accident system based onthe complex system brittle theory and establish the construction safety accident systembrittle structure model,analyse the logical contact between the brittle factors,research theformation mechanism of the safety accidents. Reveal that the existence of the factors and thebrittle contact between the factors is the root cause of the accident.Establish the construction safety accident management system,and ascertain the safetymanagement system model structure based on the analysis of the construction safety accidentsystem.The collapse of the system is because the existence of the factors and the brittlecontact.From the two points,take the falling accident for example to do a brittleanalysis.In the operation of the safety accident management system,get the analysis ofthe falling accident,give the feedback as a message to the decision-making, make atargeted accident prevention and control measures getting the cycle management controlto promote continuous improvement of the construction safety accident managementsystem.
