Abstract

The invention relates to the field of chemical grouting, and relates to a high polymer slurry parameter recognition method based on a swarm intelligence optimization algorithm, which comprises the following steps: assigning values to intelligent optimization algorithm parameters; generating a population according to an intelligent optimization algorithm rule, and assigning an initial value to eachindividual in the population, the optimization objective function value corresponding to the individual, the individual historical optimal value, the individual historical optimal objective functionvalue, the population historical optimal value, the population historical optimal objective function value and the current number of iterations; iterative solution is carried out; judging whether a predetermined number of operations are executed or whether the historical optimal objective function value of the group meets the precision requirement or not; recognizing chemical reaction kinetic parameters. According to the method, quick and accurate recognition of the chemical reaction kinetic parameters of the high polymer slurry under multiple synchronous chemical reaction conditions is realized by utilizing a swarm intelligence optimization algorithm.
