本科论文AbstractWith the progress of society,the construction industry has gradually developed into animportant pillar of China's economy.Therefore,the increasing number of employees andfrequent safety accidents not only threaten people's health,but also bring economic loss andserious impact to enterprises and society.In order to effectively prevent safety accidents,thetheory of accident cause is foundation.Enterprises should strengthen safety management.This paper starts from the control source,carries out hazard identification,combines withqualitative and quantitative analysis,evaluates the safety of construction site,and putsforward scientific safety management measures.Firstly,this paper introduces and comparesthe commonly used safety assessment methods,reviews the development of safety assessment,and summarizes the current situation of construction safety at home and abroad.Based on theconstruction safety inspection standard,hazard identification is carried out for thesubdivisional works on the construction site of Hengda yuelongtai project.Safety checklistmethod,fault tree method and LEC method are selected as the tools of this paper.The safetychecklist is used for qualitative evaluation to identify the hazard sources of Hengda yuelongtaiproject.Fault tree analysis,probability calculation and structure importance analysis arecarried out for people from falling and collapse of scaffold by using fault tree.Finally,safetyevaluation conclusion is drawn.The accident types of each sub project in the construction siteare evaluated by the risk assessment method of operation conditions.Finally,thecorresponding safety management control measures are formulated.It has important referencevalue for hazard identification,safety evaluation and safety management in engineeringpractice.Key words:construction safety;hazard source;safety assessment;pre control measures
