摘要:
基于信息熵权理论，提出采用区间熵理论定量计算风险事件发生概率及其潜在损失的基本方法，推导出区间熵和熵权公式，给出风险分析步骤，实现了对风险发生概率和损失的统一区间表达与计算，并可利用风险评价矩阵法确定风险等级。最后，以某地铁盾构法施工风险分析为例，通过计算，验证了所提出的区间熵理论在工程风险定量分析中的应用是可行的。
Abstracts:
Based on the theory of information entropy weight, a basic approach is proposed, which quantitatively calculates the probability of risk occurrence and the potential loss with interval entropy theory, then the interval entropy and an entropy weight formula are deducted. Through risk analysis steps, the unified interval expression and calculation of risk probability and loss are realized, and the risk estimation matrix is used to determine the risk levels. Finally, according to the risk analysis of a metro shield construction, the calculation verifies the application feasibility of interval entropy theory in quantitative assessment of engineering risks.
