摘要:为了探索建设工程施工安全定量评价方法，为建设工程安全管理工作提供依据和指导。本文通过对建设工程施工安全评价体系的研究，构建从指数到因素到因子的三个层次的施工安全指数体系，以期全面综合反映建设工程施工安全水平。在此基础上建立了建设工程安全指数计算模型。并通过实例分析，验证了施工安全指数能够量化、动态表述工程施工安全状况，并根据相应指标值的变化情况，剖析引起施工安全变化的内在因素，从而提出有针对性的指导意见，促进和提高精细化安全管理水平。

Abstract: The purpose of establishing safety index system is to evaluate the quality of architectural engineering & construction throughout building lifecyle management and faciliate the safety management in construction enginerring industry.Through the comprehensive research of quality evaluation of Shanghai AEC projects, the auther created the safety index system based on three levels of data including the index, the factor, and the coefficient to define the safety level of building engineering.Based on the theory, the calculation model of safety index is built.Furthermore, the safety index system of construction engineering industry is demonstrated to be a ideal tool to define and compare the building quality quantitatively and dynamicly.By studying key data, the internal factors of safety variation can be discovered and imporved, hence the project management can be upgrated onto a controllable and quantitative level.
