| 摘 要： | 采用正交试验方案和ν-SVR相结合的直接法来解决复杂坝基的初始渗流场反分析问题。通过安排正交数值试验，获取初始渗流场全面的信息，并用ν-SVR向正交试验的样本学习测孔水位和各参数之间的关系，从而建立各参数和测孔水位之间隐式表达式，用此表达式代替正算程序，经过优化最终获得最优初始渗流场。经过工程实例验证，该方法能适应非线性复杂岩土问题且具有高效性。

| Abstract: | 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. |
