摘要
用三次插值多项式确定均质土坝稳定渗流有限元计算中的自由面形状 ,用插值节点迭代确定自由面位置 ,用FORTRAN77语言编制相应的计算程序 ,经算例验证是一种可靠、高效确定均质土坝稳定渗流自由面位置的方法。
Cubic interpolation polynomial was employed to determine the free surface of stable seepage in homogeneous earth dam.Interpolation node iteration was used allocating the free surface.A FORTRAN 77 program conducted the calculation.The method was proved to be a reliable and effective one through an example.
