For the coevolution algorithm provides an evolutionary mechanism to simulate everchanging. Problem space, it is an optimization algorithm that is highly effective, especially to be applied to the optimization of plicated system of retaining and protecting for deep foundation pit. It is shown by engineering practice that the coevolution algorithm has obvious optimization effect, so it can be an important method of optimization of retaining and protecting for deep foundation pit. The authors discuss the coevolution model, object function, all kinds of constraint conditions and their disposal methods, and several key techniques of system realization.Key words: genetic algorithm。 coevolution。 optimization。 anchored row piles。 deep foundation pit1 IntroductionIn all kinds of retaining and protecting techniques for deep foundation pit, anchored row piles have been extensively used because of their some features, such as good results, strong adaptability, easy construct ion and so on. Usually, the design procedures[1] of anchored row piles are:(1)Select preliminarily the types of retaining and protecting piles and the layers of anchor, namely retaining and protecting scheme design。(2)Select preliminarily all members’ size and material parameters of retaining and protecting structure, namely detailing design。(3)Make calculation and analysis, which includes checking for embedded depth of piles and load capability of anchor, puting internal force of piles and bar arrangement , etc. , and adjusting detailing design to meet various demands of the above checking putation。(4)Compare various schemes and find out the scheme whose cost is lowest as the ultimate design of retaining and protecting for deep foundation pit .Generally, designers need to adjust severally and check repeatedly the retaining and protecting scheme and detailing so as to make every puting procedure meet all design demands. However, the design gained from this is only a “feasible solution”, but not the optimum solution in all the feasible solutions. As we known, every retaining and protecting scheme has many relevant design parameters. Moreover, these design parameters all directly or indirectly affect the investment of engineering. Hence, how to find out a set of optimization parameters to ensure economy and safety is an important problem of the design of anchored row piles, also a plicated optimization problem. For this reason, the authors introduce the genetic algorithm to the optimization of retaining and protecting for deep foundation pit [2]. Studies show that the introduction of genetic algorithm has opened a new path for the optimization of retaining and protecting for deep foundation pit [2][3]. Here, the authors explore further a coevolution algorithm that is suitable for the optimization of retaining and protecting for deep foundation pit [4].2 Model of Optimization of Anchored Row Piles2. 1 Anchored row pile system and its optimization objectiveAs a system engineering, the optimization of anchored row piles is a subsystem of the optimization system for deep foundation pit. It can be plot out two hierarchies, scheme optimization and detailing optimization. Retaining and protecting scheme, posed of row pile subscheme and anchor subscheme, is a certain bination of the types of row piles ( bored pile, artificiallyexcavated pile, precast pile etc.) and the anchor installing (without anchor, onelayer anchor, twolayer anchor and threelayer anc
