堤坝坝体的一部分(包括坝基)发生显著的相对位移或错动,最后甚至脱离原来的坝体而塌落滑出,这种现象称之为滑坡。汛期由于雨水多,水位较高,坝体部分土体被水淹没,土粒空隙被水充满,土体处于饱和状态,土粒之间粘结力减弱,抗滑能力随之降低,因此汛期出现的滑坡机率比平常要大得多,且危险性更大。所以怎样处理好汛期的滑坡有着十分重要的意义。 A significant part of the dyke dam (including the dam foundation) undergoes significant relative displacement or staggering. Finally, it slides out of the original dyke and slides out of the dams. This phenomenon is called landslide. Due to the rainy season and high water level in the flood season, part of the dam body is submerged by water, the soil void is filled with water, the soil is in a saturated state, the bond between the soil particles is weakened, and the skid resistance is reduced accordingly The probability of landslide is much greater than usual and more dangerous. So how to deal with the flood season has a very important significance.
