Because the hydraulic parameters of each component of the network are determined by a nonlinear flowformula, the solution to this system can be got by the Nexvton Raphson method.
由于管网各管段的水力参数均系非线性方程决定，因此，系统工况可采用牛顿法求解。

The generalized large well method is not applicable when the influence radius doesn't exit and the complicated hydrogeological condition is not fit to the condition of Dupuit well-flowformula.
