Abstract

In the current study, an anchored diaphragm wall design is optimized using genetic algorithm. Fixed earth support method is implemented for the design of the wall. The depth of the embedment and the magnitude of tensile force at anchor are determined. The design problem is formulated as a non-linear mathematical programming problem using FORTRAN 95. The analysis and design is carried out by varying the positions of the anchor rod. The anchor position is randomly chosen during the computation to obtain and optimize the total cost. Genetic Algorithm (GA) is employed to obtain the optimum position of the anchor based on minimum cost. The influence of different GA parameters (population size, number of generations, crossover probability and mutation probability) on the solution is studied and the results are tabulated.
