特厚表土层立井冻结方案多目标灰色局势决策

Multi-target Gray Situation Decision-making for Project Determination of Shaft Freezing in Deep Alluvium

针对特厚表土层立井冻结方案的选择尚无理论依据的现状,提出了一种将多目标灰色局势决策理论与有限元数值模拟相结合选优深冻结井冻结方案的方法。工程实例表明,该种方法具有应用简便,决策效果好等优点,为今后科学、合理地选定特厚表土层冻结方案设计提供了一种理论方法。

Aiming at the status, that there is not theory reference for project determination of shaft line freezing in deep alluvium, in the paper a method which combines the finite element numerical simulation with multi-target gray situation decision-making was brought forward, in order to optimize project determination of deep shaft line freezing. Engineering practice indicates that the method can be easily applied and has good decision-making effect. The method provides a scientific and reasonable theoretical way to determine project of shaft freezing in deep alluvium.
