梳齿坝在泥石流防治中的应用

The Application of Comb Dam to the Debris Flow Control

泥石流具有突然性以及流速快,流量大,物质容量大和破坏力强等特点,为常见的山区地质灾害。梳齿坝作为透水型拦挡坝的一种,具有部分拦挡、挡排结合的特点,可减轻坝体所受水压和冲击力,起到调节下泄流体物质组成的作用,能有效提高库容利用系数,延长坝库使用寿命,为泥石流防治的一种重要措施。

Comb dam is a permeable landslide dam which is characterized by blocking and discharge and can increase coefficient of reservoir storage capacity and extend dam service life. Therefore, it is an effective control measure for debris flow.
