Abstract: The traditional evaluation method of expressway construction site safety management standardization often ignores the uninvolved items, which affects negatively the accuracy of the evaluation results. In order to solve this problem,a comprehensive evaluation model was built based on the SPA theory. According to the comprehensive factors affecting the expressway construction site safety management, an evaluation index system was set up including construction site layout, safety protection, construction operation, bridge engineering, tunnel engineering, subgrade engineering and pavement engineering. An SPA decision matrix was established and the degree of connection and degree of generalized identity were calculated for the evaluation indexes. A certain freeway project in Yunnan was taken as an example, to which both the SPA evaluation method and the traditional evaluation method were applied. The results show that with regard to evaluation of construction site safety management standardization, a more accurate evaluation result can be obtained by using the SPA comprehensive evaluation model.
