斜坡式橡胶坝无褶皱技术研究

Studies on non-folding technology applied in slope-type rubble dam

对斜坡式橡胶坝坡脚部位的坝袋褶皱问题进行了深入研究分析,通过对橡胶坝坍坝状态和充坝状态尺寸的比较与计算,推导出一套可精确定位上下游锚固线的计算公式,从而可有效避免坝袋充水后褶皱的产生和局部应力集中的出现,使橡胶坝运行更安全,外形更美观。

In-depth study has been made on the folding of dam bag at the toe of slope-type rubble dam. With comparison and calculation of dam sizes at collapsible and inflatable conditions, a series of calculation formulas for accurate positioning of anchor lines upstream and downstream are derived. It will help to avoid folding of dam bag and concentration of local stress after it is filled with water, and also can ensure the rubber dam in a safe operation mode and good-looking appearance.
