Immune algorithm based on creature＇s immune system is an effective method to solve complicated nonlinear problems in engineer- ing.Some classical researches on immune algorithm are introduced and reviewed.The Q-s curve of single pile has complicated nonlinear features because the ultimate bearing capacity of single pile is affected by many factors.Based on the results of static load test of prestressed concrete pipe piles in Wuhan area,immune algorithm program is developed by MATLAB to predict the ultimate bearing capacity of prestressed concrete pipe piles.Calculation results are consistent with those from measurement.It indicates that immune algorithm has much more superiority than traditional algorithm in global optimization,nonlinear optimization,multi-parameter optimization.It will be widely applied in geotechnical engineering.
