库区堆积体边坡具有体积大、落差大和坡度陡的特点,对枢纽工程具有潜在威胁。以西南某电站库区堆积体为例,基于 GEO2SLOPE 分析软件对其稳定性进行计算与评价,滑速计算采用能量法和潘家铮法,涌浪高度计算采用潘家铮法和水科院经验公式法。结果表明：堆积体在蓄水工况下可能产生局部失稳,在下游19 km 集镇处产生的涌浪高度为0.63 m,但总体上形成的涌浪对下游沿岸集镇及大坝影响甚微。

Accumulation slope has the characteristics of large volume, big fall, and steep slope, w hich can induce potential threats to the key wat er projects. In this paper, the stability of an accumulation slope of a hydropow er station in southwest China w as calculated and evaluated using GEO-SLPOE softw are. The method of energy and Pan Jiazheng method w ere adopted to calculat e sliding speed, and the surge height w as determined by empirical formula method of IWH R and Pan Jiazheng met hod. The results show ed that local instabilit y can occur in the accumulation under storage condit ions and the surge height is 0. 63 m at a tow n of 19 km dow nstream. H ow ever, the surge has litt le impacts on the dow nst ream tow ns and the dam.
