提出了较系统的深基坑支护方案优选模式:利用层次分析法对各影响因素的权重值进行了求解,运用模糊综合评判方法对初选出的支护方案进行优选。结合具体工程实例,采用了系统工程中的层次分析法、多目标模糊决策理论等方法对该工程支护方案进行优化选型,不仅可以方便快捷地确定权重值,还可以降低层次分析法中人的主观性影响,使优选方法科学易行,较好地满足了实践要求。
The systematic optimization mode of deep foundation pit support scheme is put forward. The analytic hierarchy process (AHP) is used to solve the weight value of each influencing factor. The fuzzy comprehensive evaluation method is used to optimize the primary support plan. Combined with the specific engineering examples, the method of AHP and multi-objective fuzzy decision-making in system engineering is used to optimize and select the project support scheme, which can not only determine the weight value conveniently and quickly, but also reduce the influence of AHP The subjective influence, make the preferred method scientific and easy to meet the practical requirements.
