    Performance-based Risk Analysis for Subway Construction

    • 摘要: 为建立更为灵活实用的地铁工程风险分析过程,利用基于性能的地震工程(performance-based earthquake engineering,PBEE)理念提出了基于性能的风险分析(performance-based risk analysis,PBRA)方法.该方法的分析流程主要包括性能风险损失等级确定、力学响应分析、风险损失等级分析、性能风险分析4个主要部分,分析结果以性能风险等级矩阵的形式表示.与以往分析方法相比,PBRA方法具备以下优势:1)PBRA方法紧密结合风险演化的物理过程,实现了风险的全阶段量化分析;2)PBRA方法将性能水平与风险损失相对应,从而降低了确定风险损失的难度,并且使得分析结果更符合工程需求;3)PBRA方法集成了土木、交通、环境、经济、社会等众多学科的经验、理论与技术成果,为风险分析智能化创造了必要条件.

       

      Abstract: To build a reasonable and practical risk analysis for subway construction, the performance-based risk analysis (PBRA) was proposed based on the performance-based earthquake engineering (PBEE). The procedure of the method consisted of four parts including determination for performance-based classification of risk loss, and analysis for mechanical response, analysis for classification of risk loss, analysis for performance-risk. The analysis results were expressed in the form of matrix of risk classification. Comparing with the existing methods, the advantages of PBRA method lie in three aspects:(1) PBRA achieves risk quantitative analysis in whole stage because of the combination to evolutionary physical progress of risk. (2) PBRA simplifies the determination of risk loss and could better accord with requirements of engineering because of the correspondence between risk loss and performance-level. (3) PBRA offers necessary conditions for intelligentizing risk analysis because of the integration of multidisciplinary research findings of civil engineering, traffic, environment, economy and society.
