Abstract：In this paper,an improved particle swarm optimization (IPSO）was proposed.In the algorithm，the influence of neighborhood optimal particle was considered，nonlinear inertia weight decreasing strategy and learning factor dynamic adjustment method was introduced.the dam prediction and inversion of multisource monitoring data was carried using the IPSO_BP model which was formed by the improved IPSO combined with BP neural network.The results show that the convergence speed of IPSO_BP model is faster，the new model can effectively improve the ability of prediction and inversion of dam multisource monitoring data.
