摘要
根据福华山土坝的渗流观测资料,建立了测压管水位的回归统计模型,定量分析了各影响量(水位分量、时效分量)对测压管水位的影响效应。在此基础上,结合观测资料,采用有限元法反演了大坝各填筑区的渗透系数,并综合评价了大坝的渗流性态。
According to the seepage observation data, the regression statistic models of piezometric level are established to analyze the effects of water level factor and the time - effect factor in quantitative method. Based on the observation data, by the finite element method the seepage coefficient of the dam body is reversed, and then a comprehensivc evaluation of seepage behavior is made for the dam.
