| 摘 要： | 面板堆石坝的混凝土面板因温度变化产生的沿垫层滑移运动是面板内产生挤压应力的主要原因,滑移运动也对伸缩缝张开度及切向变位量起控制作用。据此提出面板浇筑温度控制原则、合理缝面结构以及伸缩缝间距和面板厚度的计算方法。

| Abstract: | The compression stresses in the face slat are mainly caused by the slip of it along the bottom cushion when the temperature is variated. At the same time, the opening of vertical joints and the tangential displacement of the face slat are influenced by the variation of temperature. On these grounds, the principle for determining the thickness of the face slat, the rational form and interval of the joints and the temperature control for casting concrete of face slat are proposed. |
