According to the mathematical model for the nonlinear second order dynamic optimal design of deformation monitoring network, a specific mathematicaI model of nonlinear second order dynamic optimal design of distance network is derived from a simple network. And gradient projection algorithm that is a kind of nonlinear optimal design technique method is put forward using solving the type of model, Thereby the solution method is popularized to solve observation weight of nonlinear second order dynamic optimal design of any deformation monitoring network.
