摘要
为解决高拱坝混凝土温控效果评价过程中存在的模糊性和随机性问题,提出一种基于云模型的温控措施效果评价方法。根据高拱坝混凝土浇筑施工特点和温降历程特征,构建高拱坝混凝土温控措施效果评价体系;运用DS证据理论确定可信度较高的指标权重;基于实测数据通过云模型对高拱坝周温控措施实施效果进行评价。工程实践表明:该评价方法有利于决策者对温控措施执行效果的全局把握,能有效地确定周温控措施的薄弱环节并指导现场温控。
In order to solve the fuzziness and randomness problems in the evaluation of concrete temperature control effects for high arch dams,an evaluation method of temperature control effects based on cloud model is presented.Firstly,the evaluation system of high arch dam concrete temperature control effects is constructed according to the characteristics of high arch dam concrete pouring construction and temperature drop history,then the D-S evidence theory is used to determine the weight of index with high reliability,and finally the model is used to evaluate the effect of high arch dam temperature control measures by cloud model based on measured data.The application in a practical project shows that the evaluation method can help decision-makers to understand the implementation effect of temperature control measures,and can effectively identify the weak links of temperature control measures and guide on-site temperature control.
