基于熵权法的深基坑支护方案优化选择

Optimal Selection of Support Scheme for Deep Foundation Ditch Excavation Based on Entropy Weight Method

本文介绍了我国深基坑支护的发展现状及趋势,总结了六大新型基坑支护方案,给出了一种基于熵权法计算权重的模糊综合评价模型,对深基坑支护方案进行了优化选择,并结合工程实际,优化选择出预应力锚杆支护方案为最佳方案,与工程实际情况一致,表明所给模型具有可操作性和推广应用价值.

This paper probes into the developing status and trend of deep foundation ditch support in china.The project of six new-type foundation ditch support schemes is summarized,which proposes a model of fuzzy comprehensive evaluation for weight calculation based on entropy weight method.This method provides a optimization selection for the project of deep foundation ditch support.And then the pre-stressed anchor support scheme is selected as the preferred scheme based on engineering practice.Consistent with the actual situation of the project,therefore,the model is proved to have operability and popularization with a certain application value.
