Design and Treatment on Asphaltic Concrete Facing of Upper Reservoir in Tianhuangping Pumped Storage Power Station
摘要
天荒坪抽水蓄能电站上水库工程地质条件复杂
除东库岸进水口范围采用喷混凝土、混凝土衬砌外
主副坝上游坡面及其余库岸和库底均采用简式沥青混凝土护面防渗。上水库运行初期共产生了34条裂缝
经修补处理后
从2001年5月运行至今
库底渗水量未见异常增大。由于沥青混凝土可快速修补
修补后没有龄期要求即可蓄水
因此采用沥青混凝土护面具有一定的优越性。
Abstract
The engineering geological conditions of the upper reservoir in Tianhuangping Pumped Storage Power Station are very complex.The simple asphalt concrete facing is adopted for whole reservoir bottom except the inlet and outlet area.There were 34 cracks on the asphalt concrete impervious face slab during the early operation period.After repairing
the seepage has not increased since May of 2001.Because the asphalt concrete can be repaired quickly and it can impound water immediately after repairing
the adoption of asphalt concrete facing has certain advantage.
