基于对长江三峡黄腊石滑坡群石榴树包滑坡的滑体滑动后的速度、滑距及涌浪的计算及其对长江的堵江危害性,对三峡大坝施工及运行期安全性和对沿岸各城镇所产生的危害性进行了分析。分析成果认为,当滑坡后出现低水位时,有堵江的可能:由滑坡产生的涌浪对三峡大坝安全没有影响,对沿岸其他各城镇影响也很小,但对巴东县城和官渡县城会造成危害。 Based on the calculation of the velocity, slippage and surge of the Shiliushubao landslide in the Huangshi rock slide of the Three Gorges of the Three Gorges and its damage to the Yangtze River, the paper analyzes the safety of construction and operation of the Three Gorges Dam, The dangers of cities and towns were analyzed. According to the analysis, when there is a low water level after the landslide, there is the possibility of blocking the river: the surge produced by the landslide has no effect on the safety of the Three Gorges Dam and has little impact on other cities and towns along the coast. However, for Badong County and Guandu County Will cause harm.
