摘　　要：BLK水电站工程电站厂房基础坐落于砂砾石地基上,基础允许承载力不高。由于水电站厂房的结构形式复杂,结构的受力和边界条件等也比较复杂,常规的结构分析方法难于准确了解结构的变形规律和应力分布,通过有限元模型做整体结构计算,对厂房沉降及承载力进行分析,并根据分析结果进行基础处理应用于工程实际。The power house foundation of BLK Hydropower Station is located on the sand and gravel foundation with low allowable bearing capacity.Due to the complex structure form of hydropower plant,the stress and boundary conditions of the structure are also complicated,so it is difficult to accurately understand the deformation law and stress distribution of the structure by conventional structural analysis methods.Finite element model is used to calculate the overall structure,and the settlement and bearing capacity of the powerhouse are analyzed.Based on the analysis results,the foundation treatment is applied to the engineering practice.
