摘要
混凝土面板堆石坝周边缝止水的损坏是其漏水的主要原因。针对工程实用形式的周边缝铜止水和ＰＶＣ止水，首次进行了承受错位变形的破坏实验，揭示了止水极限变形能力和开裂规律，提出了接缝止水的计算模型、设计准则及提高铜止水极限抗裂能力的工程措施。
Damage of perimeter joint waterstops is the principal cause of leakage in the concrete face rockfill dams.For the first time the failure tests have been performed on the F-type copper waterstop and PVC waterstop undertangential displacement. The results revealed the regularity of the waterstop rupture. The computation model anddesign criteria of waterstops are presented,and the engineering measures for increasing the limit displacement of thecopper waterstop discussed.
