Yang Qun, R China · Science Technology and Engineering · 2009
Calculation of squeezed branch pile ultimate bearing capacity by fitting loading test Q-S curves on according to the quadratic trend curve model is discussed.Genetic algorithm program was compiled,and then it was applied to optimize the parameters of quadratic trend curve model.Application shows that quadratic trend curve model is workable.The predicted curve is agree well with the field measurement curve of ultimate load;and the predicted results can be used in practice.The results also make clearly that genetic algorithm has the advantages of high calculation speed,high precision,automatic level,simple settings,high universality and etc.
