深圳红木山基坑支护设计方案优选与评价模型研究

Study on the Optimum and Evaluation Model for the Design Scheme of Deep Excavation for Hongmushan in Shenzhen

方案设计是深基坑工程优化设计中的关键环节,进行多方案比选具有明显的经济效益,基于深基坑工程的知识和经验,分析了深基坑工程设计系统的特点,运用模糊数学揭示了多目标问题的寻优理论基础,建立了深基坑工程设计方案评价指标体系,并结合具体的工程实例,简述了基坑支护方案优选的过程,为今后其他工程的设计方案优选与评价起到了借鉴的作用。

The project design scheme was a key link.Based on the knowledge and experience of deep excavation engineering,the characteristics of design system for deep excavation were analyzed.The index system for evaluating the project design scheme was established and the optimum decision-making and evaluation model was deduced from the multi-objectives fuzzy decision-making theory for the project design scheme of deep excavation and its application in the actual engineering was proved to gain superior decision result.
