摘要
根据地铁深基坑支护工程的特点,建立了支护方案评价的指标体系,并将模糊数学理论与层次分析法结合起来,构造出地铁深基坑支护方案优选的模糊一致矩阵数学模型。该模型概念清晰、理论严密、计算简便、适用范围广且评价结果客观可靠。实例分析表明,用该方法进行深基坑支护方案优选是可行的、有效的。与其它方法相比,该方法可灵活处理各种复杂的决策问题,易于编制计算机程序。
According to characteristics of bracing engineering for deep excavation of metro, using the theory of fuzzy mathematic and AHP (analytic hierarchy process), a fuzzy consistent matrix mathematic model was established to optimize bracing projects for deep excavation of metro. The model was based on clear concept and rigarous theories, and could be applied extensively to obtain objective and dependable result. A case study showed that the method was reasonable and effective to optimize bracing projects for deep excavation of metro. Compared with other methods, the present method could be used to handle all kinds of complicated decision problems, and was apt to establish the computer procedure.
