| 摘 要： | 观音岩水电站地处典型的干热河谷地区，多年平均气温为20.3℃，极端最高气温达到44℃，昼夜最大温差达到28℃，多年平均降水量为836 mm，多年平均蒸发量为2086 mm，多年平均相对湿度为64.5%。针对上述不利气候影响，在溢洪道泄槽C50抗冲磨混凝土施工过程中，通过采取综合温控防裂措施，取得了良好效果，可供类似工程施工提供参考。

| Abstract: | Guanyinyan hydropower station is located in a typical dry valley,which has an annual mean temperature of 20.3℃,an extreme maximum temperature of 43℃,a maximum temperature difference between day and night of 28℃,an annual mean rainfall of 836mm, an annual mean evaporation of 2086mm and an annual mean relative hu-midity of 64.5%. Under the impact of the mentioned adverse climate,a serial of temperature control and crack pre-vention measures were taken during the construction of C50 anti-abrasion concrete for the spillway chute,which ob-tained good results and could be well referenced by similar projects. |
