摘　　要：滑坡的分类是一切滑坡研究与治理的基础和前提。在总结分析一般滑坡的分类方法基础上,针对库岸涉水滑坡水动力条件复杂多变的特殊性,选择渗透系数k和库水位升降速率v这两个具有对立统一关系的决定性参数作为分类因子,提出了基于k/v比值的库岸涉水滑坡分类方法,并阐述了其合理性及理论意义。该分类方法将库岸涉水滑坡分为k/v>1型和k/v<1型两个类别,是一种动态的分类。该方法的提出突破了对滑坡分类的常规思维,有助于解决系统动力学在滑坡稳定性分析和预测中所面临的困境,适应滑坡稳定性研究的发展趋势,具有一定的可借鉴性和指导意义。The classification of landslides is the basis and premise for researching and treating all landslides. On basis of analyzing the general classification methods of landslides, the classification method of wading landslides of the reservoir bank is proposed based on k/v ratio, and its rationality and theoretical significance are elaborated. In the method, the complex and changeable particularity of hydrodynamic conditions of the reservoir bank wading landslide are taken into account, and the permeability coefficient k and bank water level fluctuation rate v, which are the decisive parameters with the relationship of the unity and opposite, are chosen as classification factors. Wa- ding landslides of the reservoir bank are divided into k/v 〉 1 type and k/v 〈 1 type, the method is a kind of dy- namic classification. It is a breakthrough of conventional thinking for landslide classifications that the method is proposed. The method contributs to the solution of dilemmas on the landslide stability analysis and prediction with system dynamics, can adapt to the trend of development of researches on the landslide stability, and is of some cer- tain guiding significance.
