LAYOUT DESIGN METHOD OF PILES UNDER RAFT FOUNDATION USING GENETIC ALGORITHMS

摘要

The present invention relates to a pile arrangement design method that is completed by applying a genetic algorithm to a pile arrangement design so that an optimal pile arrangement design is possible with the minimum number of piles satisfying the design criteria for basic inequality.;The present invention is a method for arranging the pile of the foundation of the lower part of the structure using a genetic algorithm, the method comprising the steps of calculating the minimum number of piles that can satisfy the bearing capacity of the foundation ground against the structure load (S11); Generating each object of the initial group represented by a combination of design variables by selectively placing the position information of each pile with respect to a predetermined number of piles on the lower foundation of the structure (S21); Searching for an optimal combination of design variables while performing hybridization and mutation processes through genetic algorithms for each individual in the initial group (S23); And calculating an inequality settled amount calculated at the time of applying the structure load to the optimal combination of design variables and evaluating whether the calculated inequality settles to meet the design criteria (S31). .;Genetic Algorithms, Piles, Batch Design, Optimization
