基于非可加测度Shapley值赋权的钻爆法地铁隧道工程施工风险灰色评价

分析了钻爆法地铁隧道施工的工作原理,依据钻爆法施工程序构建了钻爆法地铁隧道工程风险指标体系,研究了各指标之间的非可加测度权重属性,运用Shapley值赋权方法确定各指标权重。在界定地铁隧道工程风险测度的基础上,设计了风险灰色评价的方法,构建了基于Shapley值赋权的钻爆法地铁隧道工程风险灰色评价模型。利用所构建的模型对青岛地铁M1号线长江中路某区段地铁隧道工程进行风险评价,并根据评价结果提出了改进对策,同时验证了该模型的科学性。

Gray Evaluation of Construction Risk of Drilling and Blasting Metro Tunnel Engineering Based on the Weights of Non-additive Measure Shapley

The paper explores the working principle of the drilling and blasting metro tunnel engineering and establishes the risk index system based on the construction program. Then, the paper analyzes the attributes of non-additive weights of the index and use the Shapley method to determine the weights of the index system. After the risk measures of metro engineering determined,the paper designs the gray evaluation and establishes a gray evaluation of risk of drilling and blasting metro tunnel engineering based on the non-additive measure Shapley. Finally,combined with the Qingdao metro line M1 project,the paper calculates the risk value using the model. According to the evaluation results,the paper puts forward some suggestions for improvement which can confirm the scientific the model.
