摘　　要：以随机有限元法为基础，将确定性渗流场的参数视为随机变量，导出了随机渗流场的基本列式，同时推出了渗流场随机水头的均值、方差、协方差以及水头对随机变量偏导的公式，为了与结构随机分析相结合，又导出了随机渗透结点力的均值、方差与协方差及其对随机变量的偏导．Based on the stochastic finite element, the factors of the seepage field are refered as random variable, and the basic formula is worked out at the same time, the first order, the second order value and covariances of the random water head of seepage field and gradient of random water head with respect to the random variable are pointed out. In order to connecting with the random analysis of the construction, the first order, the second order value and covariances of random seepage nodal forces are put forward too.
