价格分析方法作为桥梁决策分析的重要基础,对桥梁工程的建设与维护有着决定性的影响。针对这一问题,本文引入了基于风险的地震工程理论框架,结合概率地震风险的评估方法,建立了一套能够考虑地震风险的桥梁价格分析方法,并以简支梁为例,分析了不同的桥梁维护策略对桥梁价格的影响,从概率与经济学的角度为混凝土简支桥梁的抗震性能的分析提供了一种有效可行的方法与参考,为以后进一步在此基础上发展打下了基础。
As an important basis for decision analysis of bridge, price analysis method has a decisive influence on the construction and maintenance of bridge engineering. In order to solve this problem, this paper introduces the risk-based theoretical framework of earthquake engineering, and combines with the assessment method of probability earthquake risk to establish a set of bridge price analysis method that can consider the seismic risk. Taking the simple supported beam as an example, The influence of bridge maintenance strategy on bridge prices provides an effective and feasible method and reference for the analysis of seismic performance of simply supported concrete bridges from the perspective of probability and economics, laying a foundation for further development on this basis.
