摘要
文中提出一种基于博弈论组合赋权-云模型理论的软岩隧道爆破施工风险评价体系。利用Python挖掘整理出风险指标,建立风险评价体系;通过模糊层次分析法和熵权法获得各指标的主、客观权重;进行组合赋权,优化主客观权重;基于云模型理论生成风险云图,更直观地确定风险等级。将该方法应用到实际工程,评价结果与现场实际情况相一致。
Propose a risk assessment system for soft rock tunnel blasting construction based on game theory combination weighting cloud model theory. Using Python to mine and organize risk indicators, establish a risk assessment system;Obtain the subjective and objective weights of each indicator through fuzzy analytic hierarchy process and entropy weight method;Perform combination weighting and optimize subjective and objective weights;Generate risk cloud maps based on cloud model theory to more intuitively determine risk levels. Applying this method to practical engineering, the evaluation results are consistent with the actual situation on site.
