| It is all scholars' task that makes the project economical at the precondition of ensuring foundation safe. The traditional design method of pile foundation obey the rule that "giving priority to conformation, calculation is the second", the designing parameters get by this way usually just is a kind of "feasible result", not "the best result", and if we make optimize design using the accustomed optimize method , it is restricted by own limitation of the method.As a shoring, its principle target of the Soil-Nail is guaranteeing the stability of the shoring and the being underpinned. So the estimation of the stability of the Soil-Nail shoring is the corn of the Soil-Nail design. Generally we use the limit balance theory to analysis the whole stability of the Soil-Nail, usually we calculate use horizontal after make some presumes, when searching the most dangerous slide face, the most we use are horizontal bar division method, although these methods are simple, fit for handle calculation, and have been used broadly in practices, but they are not very accurate, even sometimes get the great error.In this paper I apply Genetic Algorithms to solve the optimizing design problem of the pile foundation using Genetic Algorithms, anglicize the stability of the Soil-Nail by linking the Genetic Algorithms with the Projection Pursuit. The calculated examples proved it is feasible that applying Genetic Algorithms and Projection Pursuit to solve the deep foundation problems. |
