Abstract: Based on the statistic theory, seepage coefficient of rock and soil is considered as random variable. Therefore rock and soil can be assumed to be mixture with different seepage coefficients of isotropic media, according to the probability distribution of seepage coefficient. The contribution of rock and soil with different seepage coefficient to seepage field are determined by their probability. After determination seepage coefficient of rock and soil, water head of region and flux of section can be obtained by solution seepage equations with different seepage coefficients. As a result, the final water head of region and flux of section are weighted by the probability distribution of seepage coefficient. This method is proved by engineering example with fewer errors than FEM, so it can be another way used to analyze seepage.

Key words: probabilistic analysis, seepage of rock and soil, seepage coefficient, principle of superposition, FEM
