高寒地区混凝土双曲拱坝聚苯乙烯永久保温板施工工艺简述

摘要

Thin arch dam concrete temperature control measu-re of high alpine area is currently one of the subjects studied more widely, the main dam of Laxiwa hydropower station taki-ng polystyrene insulation board pasted on the dam downstream surface, and achieved good results. Therefore, the process has the significance of applying in the similar engineering signify-cance in the alpine region.%高寒地区高薄拱坝混凝土温控措施是国内目前研究比较广泛的课题之一，拉西瓦水电站主坝的永久保温选择了聚苯乙烯保温板粘贴于主坝上下游面，并取得了良好的效果。因此，该工艺具有在高寒地区同类工程中推广应用的意义。
