【 摘 要 】

In order to enhance the comprehensiveness and rationality of the construction risk assessment index system construction project, this paper divides the risk assessment unit according to the risk composition and risk characteristics of the accidents during the construction of the housing construction project, combined with the actual situation on site. Through the analysis of accident cases, relevant norms and standards, and the analysis of domestic and foreign literatures, the risk factors affecting the construction safety level of housing construction projects are extracted. At the same time, the theory of PSR is introduced to broaden the research scope of engineering construction risk assessment, and the construction model suitable for the construction process evaluation model of housing construction project is proposed. Based on the causal relationship of various risk factors, a systematic and scientific safety evaluation index system is constructed.
