The problem of back analysis of initial seepage field is solved by direct method based on orthogonal test and ν-SVR. By orthogonal test
the general information of initial seepage field is obtained; ν-SVR is used to study the relationship between water level and parameters; the connotative expression between them is established and used to substitute for FEM program; finally
optimal initial seepage field is obtained. Through engineering example study it
is proved that the method is efficient and suitable for solving nonlinear complicated problems of rock and soil.
