摘　　要：讨论了玛尔巴塞拱坝的崩垮与拱坝上滑稳定之间的统一性和相异性 ,分析比较了拱坝上滑稳定中的 3种不同破坏形式 ,指出玛坝沿基岩内部上滑问题比一般沿基础接触面和周边缝的滑移复杂得多。强调对拱坝上滑问题应该给予足够的重视。The article discusses the identity and difference between the collapse of Malpasset Dam and the stability of sliding upwards of arch dam,analyses 3 collapse types of the sliding upwards and points out that the mechanism of sliding upwards in the foundation rock of Malpasset Dam is more complicated than along the face of foundation rock or the peripheral joint of dam.It is emphasized that the enough attention should be paid to the sliding upwards of arch dams.
