摘要
依托天荒坪抽水蓄能电站上水库防渗工程,开展沥青混凝土面板封闭层老化研究,建立数学模型和老化方程,对其老化寿命进行预测,并针对抽水蓄能电站水库运行特点提出相应治理对策,老化的上水库沥青混凝土面板玛蹄脂封闭层通过在基面喷洒乳化沥青和涂刷新沥青玛蹄脂处理,达到了良好的修复效果。
Relying on the anti-seepage project of the upper reservoir of the Tianhuangping Pumped-storage Power Station,the research on the aging of the asphalt concrete facing sealing layer is carried out,and the mathematical models and aging equations are established to predict the aging life of the asphalt concrete facing sealing layer.The corresponding treatment countermeasures are also proposed according to the operation characteristics of the reservoir.The aged mastic sealing layer of the upper reservoir asphalt concrete facing is treated by spraying emulsified asphalt and painting fresh asphalt mastic on the base surface to achieve a good repair effect.
