| 摘 要： | 三峡库区涉水滑坡主要影响因素是水位和降雨量，也是库区滑坡体失稳的主要影响因素和诱发因素。库区每年重复着水位升降不利于滑坡的稳定，而降雨特别是大强度的降雨也诱发产生滑坡。当水位波动遇到降雨，出现工况叠加，滑坡将加剧。因此，有必要对影响滑坡变形的主导因素进行了解分析。2016年6月三峡库区全面展开了自动化监测，使得数据统计方便可靠。本文采用滑坡变形速率、降雨量、库水位变化、最大水位变化速率、淹没程度，运用灰色关联度分析法对涉水滑坡进行了计算分析。水位下降阶段，文中土质滑坡变形受库水位影响最大。水位上升阶段，该土质滑坡上部变形受降雨影响最大，下部受水位影响最大。文中岩质滑坡总是受库水位影响最大。

| Abstract: | The main influencing factors related to the fording landslides in the Three Gorges Reservoir area are the water level and rainfall, which are also the main inducing factors behind the instability of landslide bodies in the reservoir area. The annual rise and fall of the water level in the reservoir area are not conducive to the stability of the landslide, and rainfall, especially heavy rainfall, also induces landslides. When rainfall adds to the fluctuation of water level, the landslide will intensify. Therefore, it is necessary to analyze the leading factors affecting landslide deformation. In June 2016, the automatic monitoring of landslides in the Three Gorges Reservoir area was carried out, making statistical analyses of data convenient and reliable. Taking into account the variables such as the landslide deformation rate, rainfall, reservoir water level change, maximum water level change rate and submergence degree, the paper analyzes the fording landslides based on grey correlation analysis. In the stage of falling water level, the deformation of the soil landslide is greatly affected by the reservoir water level. In the stage of rising water level, the deformation of the upper part of the soil landslide is radically affected by rainfall, while the lower part of the soil landslide is affected by the water level. Generally speaking, the rock landslide is always the most affected by the reservoir water level. |
