宜巴高速公路三里花岩堆治理方案优化研究

Study on Optimization of Treatment Scheme for Sanlihua Rock Heap along Yichang-Badong Highway

在岩堆边坡治理方案评价指标中,有的为确定的数值,有的为语言评价信息,在决策过程中,对语言评价指标处理是个难点,为此,提出一种基于二元语义的岩堆边坡治理多属性决策方法。该法采用二元语义概念对语言评价信息进行处理与计算,通过计算每个治理方案对正、负理想治理方案的语义灰色关联度,最终确定最优岩堆边坡治理方案。该法具有对语言信息处理较准确的特点,较好地克服了以往对语言信息评价指标处理存在的不足。以宜巴高速公路三里花岩堆边坡治理方案决策为例,详细分析了该方法的实际应用。

Among the evaluation indexes for rock slope treatment scheme, some are defined value and some are linguistic assessment information. In the course of decision making, the handling of linguistic assessment indexes is difficult. Therefore, a multiple attribute decision making method for rock slope treatment based on two-tuple linguistic is suggested, which uses two-tuple linguistic concept to handle the linguistic assessment information and carry out related calculation. Through calculating the linguistic grey correlation degree of each treatment scheme against positive/negative ideal solution, the best one for rock slope treatment is confirmed finally. This method is characterized in correct linguistic information handling and better overcomes the deficiencies in the linguistic information evaluation indexes Rock Slope along Yichang-Badong Highway as an example, handling. Taking the treatment scheme for Sanlihua the practice of this method is analyzed in details.
