摘要针对深基坑支护方案的特点,应用模糊数学理论及最小二乘法准则构造目标函数,建立了一种适用于深基
坑支护方案综合评价的模糊优化理论模型。以某大厦深基坑支护拟用的 3 种方案评价为例,说明了该模型的应用,
并与采用其它方法得到的结果进行了对比,为施工决策者提供了一种科学有效的评判方法。

Abstract Based on the characteristics of support scheme for deep foundation pit,the objective function is
constructed with theory of fuzzy mathematics and least square method. A mathematics model of fuzzy
optimization of support scheme for deep foundation pit is established to offer a scientific and effective approach to
the managers of civil engineering. The practical example,with 3 support schemes for deep foundation pit in
Nanjing,is introduced pared to the results obtained by other methods.
Key words soil mechanics,deep foundation pit,support scheme,fuzzy mathematics,fuzzy optimization

对多个方案从多个目标的评价和选择,涉及的指标
1 前言和考虑的因素很多,存在明显的模糊性和不确定性。
如何从几个方案中选择一个相对最优的作为施工方
自从 1965 年 Zadeh 提出模糊集合(fuzzy set)的
