摘　　要：为了实现绿色建筑施工安全风险的动态分析与管理,以人员、管理、材料与技术、设备及环境5个方面为视角筛选出20个二级评价指标,并建立了绿色建筑施工安全风险评价指标体系;采用经粗糙集理论优化的层次分析法耦合熵值法的组合赋权法确定各评价指标权重;依据五元联系数的各阶偏联系数对评价指标进行集对势分析,基于集对分析理论的五元联系数建立绿色建筑施工安全风险评价模型,并结合长沙市某绿色建筑项目进行了实证分析。结果表明,该项目施工安全风险等级为较低,评价结果与调研结果一致。评价方法可真实反映绿色建筑施工安全风险评价过程中的随机性及不确定性,提高了绿色建筑施工安全风险评价的精度;评价模型可实现绿色建筑施工安全风险静态与动态评价的有效结合,为类似工程的施工安全风险评价提供参考。The given paper intends to propose a green building construction safety risk evaluation method based on the five-element connection number set analysis theory.In order to realize the dynamic analysis and management of the green building construction safety risk,first of all,after comprehensively considering the influencing factors of the green building construction safety,we have established a risk assessment index system of 6 primary indicators,including the personnel,the management,the materials and the technology,the equipment and environment,as can be listed below in 20 secondary indicators.And,secondly,in order to determine the weight of the index factors objectively and reasonably,we can describe the subjective weights and the combination weighing idea to determine the comprehensive weights of the index factors through the analytic hierarchy process of rough set optimization to the entropy method.And,then,combining the expert scoring method to obtain the probability that each evaluation index belongs to different risk levels,we can build up a safety risk identification and reverse evaluation model for the green building construction to determine the five-element connection number of the evaluation index by using the set-opposition potential of the five-element connection number and the partial connection number of each order to assess the risk level and analyze the situation under change,so as to define and determine the overall risk level and the risk development trend.And,finally,we have proposed a green building project in Changsha City for open discussion.Our assessment results demonstrate that the construction safety risk level of the project is comparatively low,which is consistent with the actual investigation results.Besides,the first level risk is easy to get overcome,for it is in an upward trend,while the other levels of risk are in a downward trend,signifying that the risk level of the project is in an advantageous trend,and easier to overcome.And,therefore,effective combination of the dynamic an
