Research On Construction Safety Hidden Trouble Management Based On Accident Causation Theory

Construction safety is an important matter related to national development,corporate image and interests of the people,and the course of construction,all types of large and small,there is always a security risk,If not from the source of the accident caused by starting,and timely investigation of all types of security risks to develop appropriate preventive measures,it is very easy to cause accidents.Therefore,based on the accident causation theory of construction safety hazards investigation and preventive measures study,reduce the incidence of accidents,has very important significance.Firstly,Based on the theory of accident causation,this paper analyzes the causes of construction safety accidents,and analyzes the causes and processes of accident formation from domino theory,trajectory crossover theory and energy accident release theory.Summed up the domestic construction safety accident nearly a decade,a detailed analysis of the 2015 China Construction casualties.Summed up the unexpected fall,collapse,and against objects in the form of three of the most common major accident,And use fishbone from human error,material defects,environmental management,environmental construction four dimensions of the three main types of construction accidents caused due to make a detailed analysis.Secondly,to clarify the links and differences between hazards and risks,From the perspective of a study on the hazards of the security risks and safety assessment methods of construction,The basic theory of the concept of hazard and classification are described,analyzed and summarized the main source of danger and on-site construction enterprises,it introduces several common methods of construction security risk assessment.For security risks set safety target discovery,the establishment of security management organization,to develop the system,security risk management and scientific measures proposed risk management in the track crossing accidents trillion theoretical model,summed up the construction site of high-risk parts of the danger signs and gives concrete actions to further effectively prevent construction accidents.Finally,Thesis based on the example of Guangshan County "12.19" template scaffold collapse,the use of fault tree analysis analyze in detail the process and cause ofsafety problems leading to the accident of the accident,according to the results of the analysis presented scientific and efficient preventive measures.Finally,the construction safety hazards investigation and corrective measures applied to real research project,find the reasons for their security risks hidden form is analyzed,and corrective measures to eliminate hidden dangers performance review.For understanding the correct understanding of the status of the safety management of construction,construction enterprises to improve safety levels,reduce the accident rate,to protect life and property safety of employees in the construction industry,there are certain practical significance.
