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。
Based on the characteristics of support scheme for deep foundation pit, the objective function is constructed with the 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 and compared to the results obtained by other methods.
