- W2383506934 abstract "In order to offset the disadvantages of low searching efficiency and large amount of calculation using traditional PSO for elastoplastic back analysis in geotechnical engineering,the comparison method of fitness value and the motion mode of individual particle of traditional PSO are analyzed and the internal factors which restrict searching efficiency pointed out.Then some corresponding improvement measures are proposed.On this basis,an improved PSO(IPSO) is put forward and used for elastoplastic parameters inverse.The results show that,compared with traditional PSO,the parameter searching efficiency and the convergence precision of IPSO have an obvious increase and the inverse results meeting accuracy requirements can be obtained with less number of iterations.Thus the calculation amount for elastplastic back analysis can be greatly reduced if using IPSO.So our proposed algorithm is a feasible method for elastoplastic back analysis in geotechnical engineering." @default.
