摘　　要：以允楞水库为例,依据坝体三排实测浸润线资料,应用弹性力学温度场理论对坝体三维渗流进行分析,通过反演拟合计算求得坝体各区拟合渗透系数,进而推求坝体在其他工况下的浸润线,为大坝稳定分析提供依据。Taking Yunleng reservoir for example, based on three row of actual saturation lines of the dam, the elasticity theory in temperature field is applied to the dambody 3-D seepage analysis, and through the inversion analysis, the permeability coefficient in dam body is obtained, then saturation lines under other operating conditions are calculated, so it provides the basis for the dam stability analysis.

关 键 词：热传导理论 坝土渗流 有限元分析
