Abstract: The optimization methods including schemes of the supporting system and the detailed calculation and design of the selected program for deep foundation pit, are studied. Using multi-objective decision making fuzzy set analysis and analytical hierarchy process, the optimized project of the retaining system that is of the multiple attribute and fuzzy property is selected. Through the selection of decision variables, objective function, constraint condition (i.e. strength, size, displacement etc.) and optimization algorithm, the detailed structure of the selected program can be optimized in order to minimize the cost of construction. By the software Matlab 6.5, it is easy to solve this minimized value of nonlinear constraint minimization value. A practical example study shows that there is better effect on both selecting the retaining program and deciding the detailed structure.

Key words: deep foundation pit, scheme of retaining system, detailed structure, optimized design
