摘　　要：目的研究建筑物整体平移施工风险评估体系,以此对平移施工风险进行有效的评估和控制.方法通过识别影响平移施工安全性的各种因素,构建多层次建筑物整体平移施工风险评价指标体系.结合模糊层次分析法和模糊综合评判法的优点,建立风险评估模型,以此估计风险概率和风险损失;引入风险损失修正参数,对风险损失等级进行修正,并通过风险矩阵结合修正后风险损失等级和风险概率等级评价建筑物整体平移施工风险;最后通过工程实例进行验证.结果利用该风险评估体系对湘江宾馆中栋整体平移施工风险进行评价,获得施工风险等级为Ⅲ级,根据风险控制准则,必须采取有效的处理措施降低风险等级.该风险评估结果与工程实际基本符合.结论建立的风险评估体系具有可操作性,能有效评估建筑物整体平移施工风险.The overall translational construction risk assessment system of buildings was studied to effectively evaluate and control the translational construction risks.First,a multilayer evaluation index system of the integral building translation construction was proposed by identifying various factors affecting the reliability of translational construction.Then,combining the advantages of fuzzy analytic hierarchy process and fuzzy comprehensive evaluation method,the FAHP-FCE method was presented for evaluating the risk probability and risk loss.Finally,the risk loss correction parameter is introduced to modify risk loss grade,and risk matrix combined with modified risk loss grade and risk probability grade is used to evaluate the integral building translation construction risk.As an example of engineering application,the construction risk level of the overall translation engineering was assessed by using the proposed construction risk assessment system.The result shows that the risk level of the overall translation construction of Xiangjiang Hotel main building is Grade Ⅲ,so effective treatment measures must be taken to reduce it.The results of evaluation are basically consistent with the actual project.All in all,the risk assessment system established in this paper is operational and can effectively assess to the overall translation engineering.
