摘要:
三峡水库处于正常蓄水运行初期时，库水位将涨落于145~175 m水位间，在库水位升降引起的剧烈变动下，将会对滑坡产生一系列不良作用，影响到库区滑坡稳定性，诱发滑坡变形。确定卡子湾滑坡的浸润线分布，分别计算降雨和不同蓄水位下的稳定性系数。计算结果表明：随库水位上升，滑坡体浸润线分布也随之上升，在降雨条件下的滑体后缘浸润线分布会受到一定影响；滑坡整体稳定性随库水位上升逐渐减小，联合降雨条件下，滑坡的稳定性系数相对减小。
Abstract:
When the three Gorges Reservoir is in the early stage of normal impoundment operation, the reservoir water level will fluctuate between 145  175 m. Under the drastic change caused by the rise and fall of the reservoir water level, it will exert a series of adverse effects and benefits on the landslide. It will further affect the stability of landslide in reservoir area and induce landslide deformation. In this paper, the infiltration line distribution of Kaziwan landslide is determined, and the stability coefficients under rainfall and different water level are calculated respectively. The results show that with the increase of reservoir water level, the distribution of infiltration line of landslide body also increases, and that the distribution of infiltration line at the back edge of landslide body under rainfall condition will be affected to a certain extent. The overall stability of landslide decreases with the increase of reservoir water level, and the stability coefficient of landslide decreases relatively under the condition of combined rainfall.
