用灰色系统理论与方法确定深基坑支护方案

根据灰色关联分析原理，将影响待决策的深基坑支护方案的众多因素的理想解指标值组成比较数列，影响深基坑支护方案决策的实际指标值组成参考数列。根据灰色优化理论模型，结合实例得出综合的深基坑支护的最优支护方案。这种灰色系统理论的方法简单，概念明确，便于应用于工程实际中。

DETERMINATION OF DEEP FOUNDATION PIT SUPPORTING SCHEME BY USING THE GRAY SYSTEM THEORY AND METHOD

According to the principle of gray correlation analysis, a comparison data series are composed by collecting the ideal index values of multiple factors of deep pit foundation supporting scheme to affect decision making, meanwhile the reference data series are also organized by collecting the actual indexes with the same effect to the decision making of foundation pit. The optimizing method on the supporting scheme is presented based on the model of gray optimal theory and combining with the practical example. The proposed method is simple with clear concept, and can be easily applied to the practical projects.
