摘　　要：根据既有房屋改建施工的工程特点,运用模糊层次分析(fuzzy analytic hierarchy process,FAHP)法,建立既有房屋改建施工安全风险评估模型。该模型实施包含6个步骤:(1)施工风险因素搜集与识别;(2)建立判断矩阵;(3)权重计算;(4)构建隶属函数;(5)计算隶属度;(6)模糊权重综合运算,最终得出既有房屋改建施工各风险因素占比,进一步确定改建施工的安全等级。通过工程实例验证,该模型和实例结果具有较好的一致性,因而,FAHP法在既有房屋改建施工安全风险评估中的应用效果很好,值得推广。According to the engineering characteristics of the reconstruction of existing buildings,the fuzzy analytic hier-archy process(FAHP)method is used to establish the risk assessment model for the reconstruction of existing buildings.The implementation of the model includes six steps:(1)collection and identification of construction risk factors;(2)es-tablishment of judgment matrix;(3)weight calculation;(4)construction of membership function;(5)calculation of the degree of membership;(6)comprehensive operation of fuzzy weight.Finally,the proportions of risk factors in the recon-struction of existing buildings are obtained,and the safety levels of reconstruction are further determined.It is verified by an example that the model and the result of the example have satisfactory consistency.Therefore,the application of FAHP method in the risk assessment of the reconstruction of existing buildings is very effective and worth popularizing.
