摘要
根据露天孤石群使用爆破法处理时,爆破效果与安全性存在不确定性的特点,通过运用以信息熵计算指标权重的未确知测度理论分别构建露天孤石群爆破效果与安全性综合评价模型,然后结合相关工程实例,对采用爆破法处理孤石群的效果与安全性进行综合评价。其结果表明:基于未确知测度理论的建立的露天孤石群爆破效果和安全性评判模型,并应用信息熵计算指标权重和采用置信度作为识别准则时,既使得爆破效果与爆破的安全性定量化,而且其评定结果更符合实际,并为类似工程孤石群处理方法的选择与安全提供了较为可靠的理论决策依据。
According to the uncertain characteristics of blasting effect and safety when blasting method was used to treat open-air solitary rock group,the comprehensive evaluation model of blasting effect and safety of open-air solitary rock group was constructed by the unascertained measure theory of calculating index weight with information entropy.Then,the effect and safety of blasting method to treat solitary rock group were integrated with relevant engineering examples evaluation.The results show that both the evaluation model of blasting effect and safety based on unascertained measure theory and the index weight calculated by information entropy and the confidence degree as recognition criteria,can not only make the blasting effect and blasting safety quantitative,but also make the evaluation result more practical.The results can provide the selection and safety of similar engineering boulder group treatment methods more reliable theoretical basis for decision-making.
