摘要
针对深基坑支护方案的主观评价指标定量化和不确定性问题,在深基坑支护方案评价指标体系建立的基础上,结合直觉模糊集理论和VIKOR理论,提出了基于直觉模糊-VIKOR理论的深基坑支护方案优化方法。该方法利用集值统计理论量化主观评价指标,采用直觉模糊集理论计算指标属性权重和专家权重,通过加权平均获取指标权重,利用VIKOR理论计算各方案的综合评价值,从而获得最优方案。将所建方法应用于扬子科创中心深基坑工程支护方案优化,获得了该深基坑工程的最优支护方案为逆作法下的地下连续墙+梁板支撑结构,为设计与施工提供了参考依据。
Aiming at the problem of subjective evaluation index quantification and uncertainty of deep foundation pit support scheme, through the established evaluation index system of the deep foundation pit support scheme, the evaluation information was converted into data by using the set-valued statistics theory, using intuitive fuzzy set theory to calculate index attribute weights and expert weights, and the index weight was obtained by calculating their weighted average.Finally, the comprehensive evaluation value was calculated by using VIKOR theory, and an optimal method of support schemes of deep foundation pit based on intuitive fuzzy set-VIKOR theory was established.Using this method, the deep foundation pit support scheme of the Yangtze Science and Technology Innovation Center was decided, and the optimal scheme was obtained as the underground diaphragm wall + beam-slab support structure under the reverse construction method.
