| 摘 要： | 三峡库区某库岸堆积体被认为是库水作用下的潜在滑坡之一．采用了GEO—seep、GEO—sigma及GEO—slope通用计算程序，对三峡水库水位升降的一系列工况下该堆积体的饱和一非饱和渗流场的变化、变形破坏机理及稳定安全系数进行了计算分析．计算结果表明，随着水库蓄水位的增加，该堆积体的稳定性会相应降低，库水骤降为其稳定性最为不利的工况．由计算分析推断该堆积体为一潜在水库新生型堆积体滑坡．

| Abstract: | Some deposit slope located at the bank of the Three Gorges Reservoir was regarded as a potential landslide affected by the water of reservoir.The article adopts all-purpose calculation programs of GEO-seep,GEO-sigma and GEO-slope,and calculates the transformation of the saturation-unsaturation infiltration field,the deformation and the safety factor of the deposit slope in different water levels of the Three Gorges Reservoir.The calculation results demonstrate that the stability of the deposit slope will decline with the rising of the reservoir water level and the stability of the deposit slope is lowest when the reservoir water level descends quickly.The calculation results show that the deposit slope will be a potential reservoir new neo-deposit slope landslide. |
