拉西瓦水电站主坝工程永久暴露面采用挤塑聚苯乙烯保温板(XPS板)进行保温。通过实验发现,XPS板覆盖下的砼内的温度和湿度随外界温度、湿度变化的幅度很小,说明XPS板的保温、保湿效果显著,能够满足大坝保温保湿设计要求。
拉西瓦水電站主壩工程永久暴露麵採用擠塑聚苯乙烯保溫闆(XPS闆)進行保溫。通過實驗髮現,XPS闆覆蓋下的砼內的溫度和濕度隨外界溫度、濕度變化的幅度很小,說明XPS闆的保溫、保濕效果顯著,能夠滿足大壩保溫保濕設計要求。

The extruded polystyrene insulation board(XPS board) for heat insulation has been used to Laxiwa main dam project permanently exposed surfaces.Results showed that temperature and humidity inside the concrete covered by XPS board did not change with outside temperature and humidity significantly,and XPS board can meet the design requirements of the dam for temperature and moisture.
