Co-Evolution Optimization of Anchored Row Files for Deep Foundation Pit

The thinking of co-evolution is applied to the optimization of retaining and protecting strutture for deep foundation excavation, and the system of optimization of anchored row piles for deep foundation pit has been already developed successfulIy. For the co-evoIution algorithm providing an evolutionary mechanism to simulate ever-changing problem space, it is an optimization algorithm that has high performance, especially applying to the optimization of complicated system of retaining and protecting for deep foundation pit. It is shown by many engineering practices that the co-evolution algorithm has obvious optimization effect, so it can be an important method of optimization of retaining and protecting for deep foundation pit. Here the authors discuss the co-evoIution model, object function, all kinds of constraint condi:ions and their disposal methods, and several key techniques of system realization.
