摘　　要：库岸边坡作为建筑地基由于受库水作用,其变形机理和变形特性对岸坡建筑变形有重要的影响。基于地基-基础-上部结构共同作用分析方法,分析了岸坡地基变形对结构系统变形特性的影响,分析表明,库水位下降速度对库岸建筑结构变形有显著影响,库水位下降速度越快,对结构变形越不利。本文研究成果对已有建筑物的安全评价、新建筑物设计及库区移民规划具有一定的参考意义。The action of reservoir water is important to the deformation mechanism of the bank slope building. Based on the soil -- foundation - the upper structure the interaction analysis method to analyze ground slope deformation effecting on the structural deformation, the research indicates rate of decline in water level have a significant effect to structural deformation of the reservoir bank, the water level fell faster, the greater the deformation of the structure. This research has certain reference significance to the safety evaluation of existing buildings, design of new building and reservoir resettlement planning.
