A deformation monitoring model for concrete dams based on PSO-ASIN

Deformation is one of the most important monitoring variables for concrete dams and widely used in dam safety monitoring. Based on standard particle swarm optimization method (SPSO), this paper presents a modified particle swarm optimization method (PSO-ASIN) using the inertia weight strategy of arcsine function. By applying PSO-ASIN to the multiple regression statistical function, this paper establishes a deformation monitoring model for concrete dams and brings this model into an engineering example. The results show that PSO-ASIN remarkably improves the algorithm performance as well as the prediction accuracy of the deformation monitoring model for concrete dams compared to the traditional least square method (LSM) and SPSO.
