简化模糊优选模型在深基坑支护选型中的应用

摘要

以模糊数学理论为基础,通过最小二乘法准则构建目标层函数,从而建立模糊综合评价模型,得出基于模糊优选理论的基坑支护方案简化优选模型,并通过工程实例验证了该模型在基坑支护方案的选取中的适用性和可靠性,以期指导实际工程.%Based upon vague mathematical theory, it sets up goal functions with least-squares approach, so as to set up vague comprehensive e-valuation model. It gets the simplified optimal model of foundation pit support plan based upon vague optimal theory. Meanwhile, it verifies the suitability and reliability of this model in the selection of foundation pit supporting plan through projects, so as to guide the practice.
