摘要
为评价混凝土拱坝水管冷却温控效果,根据混凝土浇筑到接缝灌浆各个阶段的不同特征,确立了评价指标体系,采用熵权法确定指标权重,并根据现有的温控标准,结合实际温度控制情况,运用模糊综合评价法确定水管冷却效果的评价等级。实例应用结果表明,该方法能有效判断本周水管冷却的薄弱环节,可为下周通水调整提供参考依据。
To evaluate the effect of pipe cooling temperature control of concrete arch dam,according to the different characteristics of concrete pouring to seam grouting in each stage,this paper establishes the evaluation index system.The entropy weighted method is used to determine the weight.According to the current standard of temperature control,the fuzzy comprehensive evaluation method is applied to determine the evaluation level of water pipe cooling effect by combining with temperature control situation.Application results show that the proposed method is effective to judge the weak link in cooling water pipes,which can provide the basis for next week water adjustment.
