摘要
应用最优化理论，提出了利用水头和渗流量等观测资料反演岩土体渗透参数的可变容差法．该法在近似可行概念的基础上，利用非线性单纯形法直接寻优，可以求解各类具有不同类型约束条件的优化问题．计算效率有较大提高，可解决一般实际工程渗流问题的参数反演问题．
Based on the optimization theory, a back analysis model
called flexible tolerance method is proposed for the dam and its foundation by use of the
observation data of ground water level and seepage flux. Direct optimization is performed with
the nonlinear simplex method on the basis of the approximate feasible concept. It can be used
to solve the optimization problem with all kinds of constraint conditions and is widely
adaptable, quick in convergence and highly efficient. It will be able to solve the problem of
inverting the percolation parameter in actual engineering application.
