施工期混凝土坝的温度场是复杂的非稳定空间温度场,将混凝土坝中后期冷却期间浇筑仓单测点温度动态预测模型推广为混凝土坝后期水管冷却温度时空分布动态预测模型。结合西南某建设中的混凝土坝典型坝段分布式光纤测温数据,对混凝土坝后期水管冷却温度时空分布进行预测,结果表明,基于分布式光纤测温建立混凝土坝后期水管冷却温度时空分布动态预测模型是可行的,可以方便快捷地对未来7d的温度时空分布状态和垂直向温度分布进行动态预测。
施工期混凝土壩的溫度場是複雜的非穩定空間溫度場,將混凝土壩中後期冷卻期間澆築倉單測點溫度動態預測模型推廣為混凝土壩後期水管冷卻溫度時空分佈動態預測模型。結閤西南某建設中的混凝土壩典型壩段分佈式光纖測溫數據,對混凝土壩後期水管冷卻溫度時空分佈進行預測,結果錶明,基于分佈式光纖測溫建立混凝土壩後期水管冷卻溫度時空分佈動態預測模型是可行的,可以方便快捷地對未來7d的溫度時空分佈狀態和垂直嚮溫度分佈進行動態預測。

As the temperature filed during construction period is a complex and non-stationary space temperature field,then extending the tempera-ture dynamic prediction model of the middle-later cooling period for single point on the casting storehouse to a spatial and temporal distribution dy-namic prediction model during the later pipe cooling period. Combining with the data that came from the distributed fibers of a southwest dam,it predicted the temperature spatial and temporal distribution of pipe cooling at the later stage of the concrete dam. The outcomes show that the tem-perature model based on distributed optical fiber is feasible,and it can conveniently predict temperature’s spatial and temporal distribution and ver-tical temperature distribution in 7 days.
