长江三峡库区存在许多说滑体，按滑移形态和岩层倾角关系可分为水平──近水平坡、逆向坡、顺向坡和特殊坡４大类，每一类滑坡面水平距与高程之间相关性如何是本文研究重点，利用最小二乘法原理，经对２９个不同类型滑坡统计分析，得出它们之间的相关曲线，并和实测资料进行了对比和显著性检验，其相关性非常显著，这对库区滑坡预警、预报、防治将有着很好的参考和使用价值。 There are many slip bodies in the Three Gorges Reservoir area, which can be divided into four levels according to the relationship between slipping patterns and rock dip: nearly horizontal, reverse, forward and special slopes. The horizontal distance and elevation of each type of landslide Is the key point of this paper. By using the principle of least square method, the correlation curves between 29 landslides of different types are obtained and compared with the measured data. The correlation is significant Very significant, which will have a good reference and value for landslide warning, forecast and prevention in the reservoir area.
